Comment (by azaozz):

 In .4.diff there is no need to run the content through
 switchEditors.pre_wpautop() again. We wait for TinyMCE to load, then we
 call editor.save() which serializes the iframe html, runs it through all
 filters including pre_wpautop() and places it in the textarea. At this
 point the content of the textarea is exactly the same as when autosave
 retrieves it (if the user didn't type anything).

 We need to load the content into TinyMCE and then save it back to the
 textarea as when serializing the iframe html the order of tag attributes
 may change and trigger a false positive (i.e. `<a title="..." src="...">`
 would become `<a src="..." title="...">`).
