Hovering over "Spooon" on this site no longer does transitions.
It looks like the page is trying to do feature detection, and is serving up un-prefixed 'transform' properties now. I'm not sure why.

The real issue is:
SyntaxError: Invalid regular expression: invalid range in character class:
Beautifying the source, I see failures relating to the following lines:
bO = bO.replace(/#[\w-_]+/, aA);
bO = bO.replace(/(?:::|:|\.)[\w-_()]+|\[.*?\]/, aA);

The problem here is that /[\w-_]/ is technically invalid, and we've been experimenting with slightly closer conformance to the spec in our regex engine. This appears to be breaking the web, so we'll be relaxing our interpretation of these rules again soon.
cheers,
G.

This should be fixed in r73594.
