With our new "schedule a rendering update" painting model, we need to fix code that is scheduling compositing flushes (which will trigger premature painting, and possibly affect the timing of rAF/intersection observer/resize observer).

scheduleFullEditorStateUpdate() does this, and needs to be fixed.
