Currently the spec isn't clear about this for <input>, so I don't
think it needs to specify exactly for <textarea> or contenteditable
either. It can be left as a UI decision. As far as QoI goes, I think
you'd want to display it as long as there's no visible text or images
or things. <p><br></p> should still display the placeholder, and
probably so should <p><font color=red><br></font></p>, etc. As long
as there's no text (or <img>, etc.) that's visible to the user -- if
it *looks* empty, the placeholder should display.
But this should be up to the UA.
