On open, the first tabbable element inside the dialog was never being focused in favor of the dialog container.

[ajcrews]

Within the "open" method in ui.dialog, there is an attempt to "set focus to the first tabbable element in the content area or the first button. if there are no tabbable elements, set focus on the dialog itself".

This was being accomplished using the jQuery "add" method, and was working up until jQuery 1.4.x, since: "As of jQuery 1.4 the results from .add() will always be returned in document order" (​http://api.jquery.com/add).

Also, in Firefox 3.6.x, the dialog will not show if a tabbable element is focused in the "open" method.

I had code in place to handle a race condition I was unaware of - the race condition is caused by setting the "show" option to an animation like "fade". I have addressed that issue as well.
