Thread:Feedback/Possible mock-up UI suggestion/Gmaxwell (2)

The expanding message is not on the same line as the thread title: It can't be because the drop down menu is a per-post menu not a per-thread menu. I'm presuming that the menu is on the same line as the signature, which should tend to have more space. If there is not enough space it could wrap and appear on a line of its own, making the post taller in that uncommon case (getting the HTML for that right is tricky, but possible).
