Retrieving data from attributes breaks code in Aurora 31

Tested in Aurora 31 on Windows 7, with only the extensions Firebug and FireQuery. Then, this fiddle:

You should see two console logs, but the second one will output an empty jQuery object. There’s no reason for it be empty. With FireQuery disabled, the code executes correctly and the two console logs are identical as expected.

Thank you for reporting. Unfortunately I won’t resolve this anytime soon. Haven’t been doing much webdev lately and I got busy with my other projects.

I should at least put some warnings on the website. I’m in the process of updating all my websites. Will do this in a week or so.
