Special:Undelete puts the undelete form in the same div as the content. If the
content ends with an unclosed tag which has style="display: none", the form is
hidden (since Tidy will close the tag only after the content div ends).
The fix would be to either end the content div before opening the undelete form,
or to wrap the content in an extra div.
I will add a testcase on the next comment.
