-- Can't select iframe embeds by themselves. (click enters iframe)
 - Removing link around image via button deletes image, not just link 
 - `SELECTION_CHANGE_COMMAND` not fired when clicking out of a table cell. Prevents toolbar hiding on table unselect.

+- Template drag/drop not handled when outside core editor area (ignored in margin area).
