Geoff's reduction says "font:x-small". And in older Safari and Firefox that's just an unknown font family so you fall back to the default font.

But with TOT Safari, that's treated as a size specification!

I think this is all part of changes made to fix bug 5564.

Comment 8 Dave Hyatt 2006-07-13 14:24:52 PDT

Yahoo is making use of a deliberate CSS parser hack to account for the fact that x-small in WinIE is like small in other browsers.  I believe the use of this hack may be fairly widespread on the Web.  My recommendation is that we back out the fix for 5564.

Comment 9 Dave Hyatt 2006-07-13 14:26:21 PDT

Furthermore, I know many many CSS parser hacks were closed in IE7, and this may be one of them.  This would make it even more imperative that we back out 5564.

Hixie may know how wide-spread its use is.  Adding him to CC list.

We fixed this I believe by backing out the quirky parsing.
