Autofocus is not working in Firefox

[sga]

​The documentation states:

Upon opening a dialog, focus is automatically moved to the first item that matches the following:
The first element within the dialog with the autofocus attribute
...

That doesn't work in Firefox (tested 21.0 or 22.0) or IE 10. Works in Chrome. example: ​http://jsfiddle.net/6jJAp/

Hi sga,

Thanks for taking the time to contribute to the jQuery UI project.

I see the behavior you're describing, but it works fine on ​http://jsfiddle.net/6jJAp/show in both IE10 and Firefox. I also don't see the issue using JSBin: ​http://jsbin.com/aterub/5/edit.

Were you seeing this behavior outside of jsFiddle?

I'm terribly sorry, I did a poor job debugging my case and the problem was elsewhere. The ticket is bogus.

My jsfiddle example doesn't seem to work, because it is in an iframe and I guess Firefox handles iframe focus differently. That may be a problem in itself, but it isn't the bug I was looking for.
