focus on dialog open should be constrained to the contents of the dialog
|Reported by:||jonspalmer||Owned by:||Scott González|
The open function of dialog attempts to find the first tabbable element and give it the focus via:
however if the dialog has a close icon then it will be first tabbable element and it receives the focus. Instead the find should be done on
thus.uiDialog so that the focus is applied to the contents and not the header.
might be some overlap with #3768
