The old "Cross-browser complexspiral?" page has regressed. The mouse hover
effect on links used to work but now it repaints the background incorrectly when
the hover effect is supposed to end. The error is easily visible on the test
page over the moon.

Reproducible: Always

Steps to Reproduce:
1. go to http://virtuelvis.com/gallery/opacity/old/alpha.html
2. Hover some link above the moon background image
3. Move the mouse cursor away

Actual Results:  
The background of the link is incorrectly restored (background visible through
transcludent part isn't rendered but instead replaced with a solid color).


Expected Results:  
The hover effect should be undone and the page should display as just after
loading the page.

Page is rendered correctly with 
Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0

Slow performance scrolling of the page would be bug 64401.
