Summary: Ref T13513. All queries now go through a reasonably minimal set of pathways and should have consistent behavior. Test Plan: - Loaded a revision with inlines. - Created a new empty inline, reloaded page, saw it vanish. - Created a new empty inline, typed draft text, did not save, reloaded page, saw draft present. - Created a new empty inline, typed draft text. Submitted feedback, got prompt, answered "Y", saw draft text submit. - Created a new empty inline, typed draft text, scrolled down to bottom of page, typed non-draft text, saw preview include draft text. - Marked and submitted "Done". - Used hide/show on inlines, verified state persisted. - Did much of the same stuff in Diffusion, where it all works the same way (except: there's no prompt when submitting draft is-editing inlines).
