Sorry Bernd, i wasn't meaning for that to be a "please fix" email, more 
of a "this is what i find, what do the specs say?" though it sort of 
degenerated towards the end (i had somehow not absorbed this bit 
http://www.w3.org/TR/CSS21/tables.html#q4 when reading that page last 
week). Maybe i can plead temporary insanity :-)

I hadn't come across this part of the spec. Maybe I skipped it since it 
looked like it was for implementors only. Don't know, but it smells of 
saying 'we're going to make the specification be whatever has already 
been implemented, so normal rules don't apply here' :-(
If starting with a clean sheet and not having backwards compatibility 
with existing content to worry about, would the specification still say 
that?

I don't understand why a box with style table-cell should not overflow 
like other boxes. Creating an inner div just looks like a work-around.
Codifying existing practice into 'specifications' just seems wrong. I 
notice it also happened with the table border models from CSS 2 to CSS 
2.1 (but the original choice was arbitrary in the first place, and 
separated borders are less flexible since you can't easily put borders 
around rows & columns)

I downloaded the latest nightly and it works (albeit with a couple of 
minor graphical anomalies) :-)
