to upload using the `html4` Plupload handler.
The HTML4 Plupload handler uses a hidden iframe to POST the upload form, and
unfortunately Internet Explorer 9 doesn't support the `application/json`
content-type which `wp_send_json_success()` and requires `text/html` instead.
This partially reverts [30354], keeping the better error messages.
Merges [31429] to the 4.1 branch.
Fixes#31037.

If the token is set (`$keep` is a string), this means the user is viewing their own profile-editing screen and destroying their own sessions (except the current one). If it isn't set (`$keep` is null), the user is editing another user's profile and destroying all of their sessions with no exceptions.

* Variables in DocBlocks should be backtick-escaped
* Parameter and return types should be as specific as possible
* `@param` types and variables should align with each other, but not intentionally with the `@return` description

* Use a `MutationObserver` to listen to the `body` class of the parent editor frame.
* In `wpview_media_sandbox_styles()`, only return the MEjs stylesheets.
* In `wp_ajax_parse_media_shortcode()` and `wp_ajax_parse_embed()`, return an object instead of an HTML blob to allow passing `body` and `head` separately

* Add a setting to `_wpMediaViewsL10n.settings`: `mediaTrash`
* In the attachment edit modal, properly toggle between Trash/Untrash
* In `media.view.Attachment`, add a method for `untrashAttachment`
* When creating the grid toolbar, switch the setting order of subviews so that `media.view.DeleteSelectedButton` can listen to the instance of `media.view.AttachmentFilters.All` to update the text in its UI.
* Add a new filter to `media.view.AttachmentFilters.All`, `trash`, when `settings.mediaTrash` is true
* Allow the cached queries in `Query.get()` to be flushed when race conditions exist and collections need to be refreshed. This is currently only being used when `MEDIA_TRASH` is set, to refresh the filtered/mirrored collections related to `all`, `trash`, and any already queried filter.
* Cleanup the bootstrapping of `media.view.MediaFrame.Manage`
* Allow `wp_ajax_query_attachments()` to return items from the trash when `MEDIA_TRASH` is `true`
* Allow `wp_ajax_save_attachment()` to set `post_status` when `MEDIA_TRASH` is `true`. It allows `wp_delete_post()` to be called, which will trash the attachment instead of deleting when the flag is set.
Props koop for the knowledge sharing and thought partnership.

We will no longer replace previously valid oEmbed responses with an `{{unknown}}` cache value. When this happens due to reaching a rate limit or a service going down, it is data loss, and is not acceptable. This means that oEmbed caches for a post are no longer deleted indiscriminately every time that post is saved.
oEmbed continues to be cached in post meta, with the addition of a separate meta key containing the timestamp of the last retrieval, which is used to avoid re-requesting a recently cached oEmbed response. By default, we consider a valued cached in the past day to be fresh. This can greatly reduce the number of outbound requests, especially in cases where a post containing multiple embeds is saved frequently.
The TTL used to determine whether or not to request a response can be filtered using `oembed_ttl`, thus allowing for the possibility of respecting the optional oEmbed response parameter `cache_age` or altering the period of time a cached value is considered to be fresh.
Now that oEmbeds are previewed in the visual editor as well as the media modal, oEmbed caches are often populated before a post is saved or published. By pre-populating and avoiding having to re-request that response, we also greatly reduce the chances of a stampede happening when a published post is visible before oEmbed caching is complete.
As it previously stood, a stampede was extremely likely to happen, as the AJAX caching was only triggered when `$_GET['message']` was 1. The published message is 6. We now trigger the caching every time `$_GET['message']` is present on the edit screen, as we are able to avoid triggering so many HTTP requests overall.

* In `wp_ajax_add_tag()`, `$post_type` is set and never used.
* In `wp_ajax_hidden_columns()`, `$hidden` is set twice, but only checks for the existence of `$_POST['hidden']` the first time. The two lines can be combined and work together.
* In `wp_ajax_inline_save()`, `$mode` is set and never used.
* In `wp_ajax_find_posts()`, `$searchand = $search = '';` is leftover cruft, neither variable is used. `$wpdb` does not need to be imported, it is never used.
