See the attached test case.  Try to activate the link using either mouse or tab.  The border of the link appears through the first div which has bigger z-index value.

Happens both in FF3.0a5 and on the trunk.

Reproducible: Always

Steps to Reproduce:
1. Load the attached test case.
2. Press tab to activate the link.
3. The link border appears through the yellow div.
4. Click a blank part of the page to deactivate the link.  Now, right click the link.
5. The border again appears through the yellow div.
Actual Results:  
The link border is not masked through the higher z-index opaque div.

Expected Results:  
The link border should be covered by the higher z-index opaque div, just like its text is.
