I think this bug lies in RenderTextControl::calcPrefWidths().
It's better to use tmAveCharWidth rather than "using 0 as the nominal
character"

Also, in order to match IE, Firefox use "tmAveCharWidth * size + tmMaxCharWidth
- 4" as the actual pixel width of the input text filed.
The code is here:

in nsTextControlFrame::CalcIntrinsicSize
