Summary: Ref T13513. As users type text into inline comments, save the comment state as a draft on the server. This has some rough edges, particularly around previews, but mostly works. See T13513 for notes. Test Plan: Started an inline, typed some text, waited a second, reloaded the page, saw an editing inline with the saved text.
