Changeset link incorrectly found in wiki page title

As a repo owner I was creating wiki page Meetings/2012-10-17.wiki.

In the screenshot there is some unclosed tag generated by your wiki before title written by me. The problematic html and wiki page part are highlighted in screenshot.

Desired outcome:
There should only be plain text title. There shouldn't be 20121017"> text before the title.

Actual outcome:
There is an unclosed <a> tag at the beginning of the wiki page messing up the wiki page text.

I think the part of filename that goes into <h1 id='...'> (namely the date part 20121017) is considered as a reference to changeset.
