This sounds like a browser bug or at least a feature request.  Adjusting 
font size to greater than the line height would ideally increase the line 
height to at least the new font size.

The other issue, however, is that use of absolute positioning on a page 
frequently results in some text overprinting or obscuring other text or 
in text clipping if text size in the browser is greater than what the 
website was designed to accommodate.
