Description of problem:

When viewing a bug in firefox3 I get quite large fonts for the bug heading and comment fields. Their font size does not seem to respect browser settings. As reading comments is what we do most with bugzilla I find it very annoying.

Version-Release number of selected component (if applicable):
firefox 3.0.1
the same behaviour can be produced with firefox2

How reproducible:
Always

Steps to Reproduce:
Set fixed font size (or even all font sizes) to some extreme value to see the difference, say to 9pt/72pt.
  
Actual results:
Comments and heading remain the same size.
While the rest of the page adjusts according to new setting.

Expected results:
Font sizes should follow user settings.
