Sergey Biryukov 54e45457a8 Editor: Trigger the tinymce-editor-init custom jQuery event on DOM ready.
Otherwise TinyMCE may initialize earlier and handlers attached on DOM ready may not get triggered. Fixes making the editor menu "sticky" and setting/resetting some screen options on the old Edit Post screen.

Props azaozz, majhajob, sabernhardt.
Merges [49911] to the 5.6 branch.
Fixes #52046, #51995.
