  AX: cannot use accessibility to focus an element in a cross-origin iframe

Reviewed by Tyler Wilcock.

If you use VoiceOver to navigate to a text field inside a cross-origin iframe, the field doesn't automatically get keyboard focus. The issue is that Element::focus checks whether the frame has had previous user interaction. To fix it, we can just mark the accessibility focus request as a user gesture.

The test needs to be in http/ because otherwise it's not possible to create a cross-origin iframe.
