Test case: http://www.webblaze.org/tests/alias/

Browsers that alias: Firefox 3, Safari 3.1.2, Chrome.
Browsers that do not alias: Internet Explorer 7, Opera 9.5.2

This looks like a Firefox-ism that I copied into WebKit.  We added
aliasing to WebKit because, without it, we failed a regression test.
I'll investigate whether that test is based on a real web site.  Jonas
has previously said he thinks the aliasing is important for web
compatibility.  Jonas, do you know of actual web sites that will break
if we follow the current HTML 5 text?
