Attachment: testcase

Minimized testcase.  I don't fully understand the interaction, but two things I
note in the testcase:

1) Removing the border-collapse CSS on the TABLE tag fixes the page, or
2) Removing the extra TBODY tag from the HTML code also fixes the page.

->Layout, as it does not appear from the testcase to be a fonts/text issue at
the core.

An empty tbody really seems to break border-collapse tables quite badly.  Notice
the lack of borders in this testcase.
