Post submission quirk

[srmalloy]

I haven't experimented to see whether this happens all the time when you comment on a post that's not on the last page of a thread, or only happens when new replies come in while you're writing a comment on a post that's not on the last page of a thread and don't show the new replies, but you can click the "Submit" button, and all you'll see is the button change, then revert to "Submit", without being taken to your new comment, and with no indication that the submission was successful, so that you're likely to click the "Submit" button again because something clearly went wrong... and then have to hide the double post when you check on the last page.
