[Camino] CSS opacity apparently broken in trunk

[Sebastian Winkler]

It appears to me that CSS opacity is broken in the trunk build at
http://ftp.mozilla.org/pub/mozilla.org/camino/nightly/latest/
whereas it works fine in the Universal trunk version at
http://ftp.mozilla.org/pub/mozilla.org/camino/nightly/experimental/ 
latest-Test-1.8-Uni/

This disfigures my own humble site (http://www.weblab.pt/) in my  
favorite browser as it makes extensive use of CSS opacity.
