Refinements for asynchronous rendering in `wp.mce.media.PlaylistView`:

* Add `visibility: hidden` as an inline style to `<audio>` tags, there is a race with the stylesheet which can get enqueued in the body and loaded in the footer.
* When creating new instances of `MediaElementPlayer`, always push them onto a stack. Lone views can be responsible for multiple instances of the same shortcode on render.
* Rename `wp.media.mixin.unsetPlayer()` to `wp.media.mixin.unsetPlayers()` to reflect the above.
* Call `wp.media.mixin.unsetPlayers()` on the view's `unbind()` method, instead of inline in the `render()` method
* Make sure `WPPlaylistView` is instantiated for each editor instance
* Ensure that the `No Items Found` view state is not rendered when attachments actually do exist.

Persisting `<track>` elements as the body of a `[video]` shortcode in MCE Views:

* When generating the view's HTML, ensure that the shortcode's `content` is added to the model
* Add a `PostProcess` event in the `wpview` plugin to properly return the shortcode when the editor mode is toggled, ensuring that elements in the body are not dropped.

Force users to choose a nav menu in the custom nav menu widget, for a better customizer UX

Before, they had to make a dummy change to get it to render. Now they
are made to choose a nav menu from the dropdown, which feels more
natural.
