 In [changeset:"55179" 55179]:
 {{{
 #!CommitTicketReference repository="" revision="55179"
 Editor: Separate content styles for iframe in
 __wp_get_iframed_editor_assets() and wp_default_styles().

 This changeset:
 * Removes the `'wp-block-editor'` and `'wp-block-library'` from the
 iframe's stylesheet collection (i.e. `_wp_get_iframed_editor_assets()`).
 * Adds the new `'wp-block-editor-content'` for the separate stylesheet to
 the list of editor (`'wp-edit-blocks'`) dependencies.

 Why?

 These PHP changes are part of the initiative to:

 * Separate the content styles contained in the block editor package into a
 separate stylesheet.
 * Avoid loading all block editor styles into the iframe.

 Fixes #57550.
