Attribute selector in "is" not working in firefox

Should be true in Firefox, works in other browsers and in Firefox for 1.4.2.

The documentation for ​attribute-selectors says:

Attribute values in selector expressions can be written as bare words and must be surrounded by quotation marks.

So if you do that and change your test accordingly to use quotation marks around the attribute value it works in all browsers.

Thanks, that helps. I guess I've just got into the habit of not using quotes coming from working with css where it appears to be optional in the standard, and until now has worked fine in jquery.

This bug can probably be marked as invalid.
