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.

* Introduce `WP_Customize_Manager::get_nonces()` to consolidate logic for retrieving nonces.
* Export nonces centrally in `wp.customize.settings.nonce` with each request and update nav menus preview to utilize.
* Send updated nonces to preview upon `nonce-refresh`.
* Request full preview refresh if Nav Menu selective refresh request fails (e.g. due to bad nonce).
* Update nav menus and widgets in Customizer to utilize `customize_refresh_nonces` for exporting nonces and keeping them up to date.

Add widget controls with an initially-true `active` state so that calling `expand()` will not be short-circuited. Previously the `active` state would be set once the preview refreshes, but this happens too late for the `addWidget` call. Fixes regression introduced in [35231].

For accessibility, UI controls should preferably be native controls. Adds
ARIA attributes and labels to improve accessibility and pair these buttons
with the ones in the Menu Customizer.

Widgets panel will not wait to display until the preview loads.
Also fixes problems with `margin-top` in panels where other panels' `active` states change, as well as ensuring sections of deactivated panel collapse before panel is hidden to prevent the pane from becoming empty of controls.

In 4.3 the widget controls were fully initialized up front along with the sidebar controls. The sidebar control depended (unnecessarily) on the widget control to ensure that `wp.customize.Widgets.savedWidgetIds` was defined. So after [34563] there could be a situation where the widgets are added/removed from a sidebar before their controls are initialized (if the sidebar section is never expanded), resulting in an error attempting to get a property off of an undefined value. So this change does the right thing and defines `savedWidgetIds` up front.
Also changes the `savedWidgetIds` variable type from an array to an object, to match how it is used as a dictionary lookup.

The Menu Customizer feature includes a performance technique whereby the controls for nav menu items are only embedded into the DOM once the containing menu section is expanded. This commit implements the same DOM deferral for widgets but goes a step further than just embedding the controls once the widget area's Customizer section is expanded: it also defers the embedding of the widget control's form until the widget is expanded, at which point the `widget-added` event also fires to allow any additional widget initialization to be done. The deferred DOM embedding can speed up initial load time by 10x or more. This DOM deferral also yields a reduction in overall memory usage in the browser process.
Includes changes to `wp_widget_control()` to facilitate separating out the widget form from the surrounding accordion container; also includes unit tests for this previously-untested function. Also included are initial QUnit tests (finally) for widgets in the Customizer.

* Ensure that a Custom Menu widget selecting a newly-inserted menu gets updated to use the new menu ID upon Save & Publish.
* Dynamically update the visibility of the Custom Menu widget's "no menus" message when the number of menus changes between 0 and 1+.
* Send all dirty Customized settings in `update-widget` Ajax request and `preview()` them so that the widget update/form callbacks have access to any data dependencies in the current Customizer session (such as newly created unsaved menus).
* Update link in Custom Menu widget to point to Menus panel as opposed to Menus admin page, when in the Customizer.
* Fix an issue with extra space at top immediately after creating new menu.
* Fix doubled `update-widget` Ajax requests when changing select dropdown; prevent initial from being aborted.
* Add missing `wp_get_nav_menus()` hooks to preview Customizer updates/inserts for `nav_menu` settings; includes tests.
* Update `wp_get_nav_menu_object()` to allow a menu object to be passed in (and thus passed through).

This was broken since 4.0 and the introduction of user session tokens. The nonces are now tied to session tokens as opposed to user IDs, and thus they change with each re-login.
Custom nonces can be added through the `customize_refresh_nonces` filter. On a successful refresh request the JavaScript API will trigger a `nonce-refresh` event. See widget's update nonce as an example.

The current logic doesn't account for the special case of `select[multiple]` inputs which lack a single value to synchronize: The value to synchronize is an array of zero or more values.
This change replaces `_getInputStatePropertyName()` with `_getInputState()`, which returns the state for an input depending on its type, and `_setInputState()`, which updates an input's state based on its type.

jQuery does nothing when calling `slideUp` on elements that are not inserted into the DOM yet, which can now be the case now when first loading the Customizer as the panels, sections and controls get dynamically inserted, see #28709.

Control can indicate its active state by a subclass overriding the 'active_callback' method, by supplying a callable 'active_callback' argument into the control's constructor, or by filtering 'customize_control_active'.
