Comment 2 for bug 918452

Apparently that patch isn't really correct, and this is a behavior difference between chrome and firefox at least. I've about reached the end of my css skill already so maybe someone else has thoughts.

Googling around a bit I did find these which may be relevant (possibly fixed in firefox 10)
