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.

> mark the accessibility focus request as a user gesture Does this mean that any script that runs as a result of that focus also gets the user gesture permissions?

(In reply to Simon Fraser (smfr) from comment #6) > > mark the accessibility focus request as a user gesture > Does this mean that any script that runs as a result of that focus also gets > the user gesture permissions? Good question. Yes, but that'd be no different than if the user pressed Tab to focus the same control and that triggered a script. Actions triggered by assistive technology should have the same effect as actions triggered by a keyboard or pointing device.
