If you use a transparent gif in a input tag of a form, the transparancy is 
replaced by a white background.


Sample:
<span style="background:#FF0033"><input type="image" src="print.gif"></span>

where print.gif is a transparent gif (see URL)


The sample does not contain a border attribut. If you add an border='0' 
attribut to the input tag, about half of the gif is transparent, the other 
half remains white. 

Reproducible: Always

Steps to Reproduce:
1. execute the URL in mozilla 1.2
2.
3.

Actual Results:  
gif has a white background

Expected Results:  
gif should have a red background

worksforme, linux trunk build.  Is this a problem with the WinXP "themed"
controls only?  Does the same problem happen on other Windows versions?
