Description

A user of mine first reported this problem. Apparently, if you click buttons fast enough, you get the error, "ExpatError: mismatched tag: line 386, column 551".

Steps to reproduce

  1. Go to the WikiSandBox page, then edit it as plain text.

  2. A couple options here:
    1. Click "GUI mode". Before the text edit pane is rendered, click "Text mode".
    2. Double-click "GUI mode", then quickly click "Preview".

Obviously, it's easier to do this if you have a slow connection to the Wiki server. Mine is about 20 ms away as the packet flies and is running completely standalone. I can also reproduce the problem against moinmo.in.
