Subject: [PATCH] Editor: when TinyMCE is used, add `autocomplete="off"` to the
 textarea to prevent problems with missing <p> tags when the user reloads the
 page or uses Go Back/Go Forward buttons, and when editing the same post from
 two different windows. The autocomplete can be removed with the `the_editor`
 filter. Part props xsonic, fixes #27251.
