User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.1) Gecko/20061204 Firefox/2.0.0.1

Example:
<div style=width:100px;background-color:red;overflow:auto;>Spacer Line<br><a href=#>MOUSE DOWN ON ME</a></div>

When mousedown event occurs on link, a pixel border is added that counts towards the div's (block element) inner-size, but not actual size, forcing it to overflow and show the scrollbars.

Reproducible: Always

Steps to Reproduce:
1. See Example
2. Mouse down or click on link
3. See scrollbars added
Actual Results:  
Scrollbar is added

Expected Results:  
No scrollbars should be added... pixel border should not count towards element sizing
