Need to figure out what escaping webkit supports for querySelector, e.g. so you can match

<foo:bar> or <foo.bar>

The way to do this is

querySelecto('foo\\:bar') or querySelector('foo\\.bar'). (Escape the character which , which itself needs to be escaped (weee....).

Need to update the selector parser to support this.

If anyone hits this bug, star it and add a comment that you'd like it fixed. (I'm not sure anyone is going to ever need this).
