Autofocus no longer working in modal

[haquex19]

Bug description:

Starting with the newest release (2.2.0) the autofocus attribute is no longer working. I have a modal window that has a few form elements including a button and an input field. I add the autofocus attribute to the input field and it does not focus. This was working correctly in version 2.1.4

Link to minimally-working plunker that reproduces the issue:

Notice how the button is focused, whereas the input field should be focused since it is the one with the autofocus attribute

Version of Angular, UIBS, and Bootstrap

Angular: 1.5.8

UIBS: 2.2.0

Bootstrap: 3.3.7
