.css('font-size') incorrect when Mozilla Firefox applies minimum font size

Description

The .css('font-size') should return the font-size rendered by the browser. But on Firefox (3.0.15, Ubuntu Jaunty), when the font-size of an element is below the browser's minimum font-size, the function incorrectly returns the font-size set by the CSS, whilst the rendered element is actually bigger.

Attached file shows the difference between this function's value, the CSS given to the element, and, in order to measure the actual rendered font-size, the height as calculated by .height() This example gives the element a font-size of 5px, so the browser's minimum needs to be greater. Default on Firefox is 10px I believe.

Opera gives the correct values (default minimum is 9px), haven't found min font size options for IE / Chromium.

I am not convinced this is incorrect behavior.

If this is a bug, it’s a bug in Firefox, not jQuery.
