The Customizer and Theme Installer open in full overlays that need to receive
focus. Also, keyboard navigation should be constrained within the overlays. Using
CSS `visibility` to hide all the content except the overlays, makes them the only
available and focusable content and allows browsers to handle focus natively.

* Eliminates the server mutating the a `WP_Error`'s `$error_data` to merge-in a `$from_server` flag (since it may not be an array to begin with). Instead it defers to the client to add a `fromServer` param on any `Notification` instances created from server-sent errors.
* Ensures that notifications will be re-rendered if a notification's `message` changes but the `data` and `type` remain the same.
* Adds explicit support for the `Notification` class to have a `setting` property, ensuring that the property is set whereas previously it was dropped.

WordPress maintains the minified version of jquery.masonry.js since there is no official build, however it has been excluded from grunt's minification process. This adds a minification task to grunt, adds it to the precommit hook for JS, minifies the file, and bumps the version on jquery.masonry.min.js. The change to the non minified version was introduced in [38261].

[38179] added support for the rainbow flag to core, but platform compatibility is a bit strange, because the flag was defined out of sync with the usual Unicode release cycle. For example Android N supports all Unicode 9.0 emoji, but doesn't support the rainbow flag thus the rainbow flag isn't rendered.
The Twemoji loader already has an exception for flags - it'll load if the browser supports everything but flags, and then only replace flag emoji, leaving everything else as native rendering. To provide a seamless experience for all flags the loader now uses the rainbow flag to test flag support.

Previously, changing the post thumbnail of a published post in the edit screen
would immediately apply the change, rather than waiting for the post to be
saved before applying the update. This could lead to someone unintentionally
editing the post thumbnail on a published post, and made it impossible to
preview changes to post thumbnails on published posts before saving the change.
This introduces a new Ajax handler, `wp_ajax_get_post_thumbnail_html()` to
retrieve the HTML for the post thumbnail meta box without updating the post
meta value for `_thumbnail_id`. It also allows post thumbnail changes to be
previewed by passing the `_thumbnail_id` as a query variable to the preview
screen and adding a new filter, `_wp_preview_post_thumbnail_filter()`, which
gets applied to `get_post_metadata` during the post preview process.

This is a follow up to [38065] to ensure that `wp.html.string()` always
converts empty `alt` attributes to `alt=""` rather than returning HTML using
empty attribute notation, like `alt`. This allows screen readers to ignore
images with empty `alt` attributes, rather than reading out the URL string.
Additionally this completely removes the logic in `wp.html.string()` for
converting blank attributes to empty attribute notation since empty attribute
notation is generally meant to denote a boolean value, e.g.,
`checked` == `checked="checked"`, which doesn't apply in this context because
boolean attributes must be omitted in order to represent a `false` value.

Previously, when inserting an image from a URL, leaving the `alt`
field blank in the media modal would result in an image being
inserted into the editor without an `alt` attribute, rather than
an empty `alt`. This happened because the `props.type` would not
get set in `wp.media.string.props()` — because `attachment` is
undefined in this case — causing the image fallbacks to get
skipped.
This fixes the issue by explicitly setting `props.type` to 'image'
in `wp.media.string.image()` before filling out the rest of the
properties.

When a setting is invalid, not only will it be blocked from being saved but all other settings will be blocked as well. This ensures that Customizer saves aren't partial but are more transactional. User will be displayed the error in a notification so that they can fix and re-attempt saving.
PHP changes:
* Introduces `WP_Customize_Setting::validate()`, `WP_Customize_Setting::$validate_callback`, and the `customize_validate_{$setting_id}` filter.
* Introduces `WP_Customize_Manager::validate_setting_values()` to do validation (and sanitization) for the setting values supplied, returning a list of `WP_Error` instances for invalid settings.
* Attempting to save settings that are invalid will result in the save being blocked entirely, with the errors being sent in the `customize_save_response`. Modifies `WP_Customize_Manager::save()` to check all settings for validity issues prior to calling their `save` methods.
* Introduces `WP_Customize_Setting::json()` for parity with the other Customizer classes. This includes exporting of the `type`.
* Modifies `WP_Customize_Manager::post_value()` to apply `validate` after `sanitize`, and if validation fails, to return the `$default`.
* Introduces `customize_save_validation_before` action which fires right before the validation checks are made prior to saving.
JS changes:
* Introduces `wp.customize.Notification` in JS which to represent `WP_Error` instances returned from the server when setting validation fails.
* Introduces `wp.customize.Setting.prototype.notifications`.
* Introduces `wp.customize.Control.prototype.notifications`, which are synced with a control's settings' notifications.
* Introduces `wp.customize.Control.prototype.renderNotifications()` to re-render a control's notifications in its notification area. This is called automatically when the notifications collection changes.
* Introduces `wp.customize.settingConstructor`, allowing custom setting types to be used in the same way that custom controls, panels, and sections can be made.
* Injects a notification area into existing controls which is populated in response to the control's `notifications` collection changing. A custom control can customize the placement of the notification area by overriding the new `getNotificationsContainerElement` method.
* When a save fails due to setting invalidity, the invalidity errors will be added to the settings to then populate in the controls' notification areas, and the first such invalid control will be focused.

Eliminates JS logic (from [36698]) which attempted to do pure JS update while waiting for the selective refresh response to return. The duplicate JS logic lacked a re-implementation of the `image_downsize()` functionality available in PHP, and so the JS preview logic would fail to properly preview images that didn't have the exact theme image size generated. To keep the code DRY and to eliminate the momentary display of an improperly-sized image, the duplicated JS logic is now removed.

Backbone, from 1.1.2 to 1.2.3. Underscore, from 1.6.0 to 1.8.3.
The new versions of Backbone and Underscore offer numerous small bug fixes and some optimizations and other improvements. Check the [http://backbonejs.org/#changelog Backbone changelog] and [http://underscorejs.org/#changelog Underscore changelog] for the full details.
The new versions include some significant changes that may break existing code. Plugins or themes that rely on the bundled Backbone and/or Underscore libraries should carefully check functionality with the latest versions and run any available unit tests to ensure compatibility.
Some changes of note that were addressed in core as part of this upgrade:
* `_.flatten` no longer works with objects since Underscore.js 1.7. `_.flatten()` working with objects was an unintended side-affect of the implementation, see [https://github.com/jashkenas/underscore/issues/1904#issuecomment-60241576 underscore#1904]. Check any `_flatten` usage and only flatten arrays.
* As of Backbone 1.2.0, you can no longer modify the `events` hash or your view's `el` property in `initialize`, so don't try to modify them there.
* Since Underscore 1.7, Underscore templates no longer accept an initial data object. `_.template` always returns a function now so make sure you use it that way.
