I found out why it is doing it. That menu you’re using attempts to insert a form directly inside an unordered list. That is horribly invalid HTML (the form should be inside a list item when it occurs inside a list element). Thus the html parser we use attempts to fix the error by closing the unordered list before inserting the form. Not sure if there is much I can do about that, but I do have one idea I’m going to try.

I WAS able to get the menu to work again by just removing the ending ul tag. However, that puts the html in even worse shape, and the “fixes” that the xml parser did trickle down even farther than that, so I’m afraid there is no way I can fix this from my end.
