 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.
