Yeah, that seems like a bug in the CSS border rendering for tables. I 
recommend filing a bug at http://bugs.webkit.org/. Feel free to cc me 
(ian at hixie.ch is my account).

It's a CSS bug, not an HTML bug.

The above spec, or this version of it (it's basically the same document):

   http://www.whatwg.org/specs/web-apps/current-work/complete/tabular-data.html#table-model

...describes the semantics of the table (including what cells it has), but 
as far as rendering the borders go, CSS is what matters, specifically in 
this case the collapsed border model:
