btw, the buttons are reversed ("Remove" is the cancel button and "Cancel" is the
ok button).

I don't think that this restores the previous behavior, because before you had
to press tab to get focus on the remove button.

Also, I don't think this regression is impactful enough to warrant a merge.

i think this is better than the previous behavior as it's what all settings
dialogs do
that's fine by me

we looked at this together and it's not quite the same.  fixing this dialog to:
- handle enter
- focus on first tab

   uber.invokeMethodOnParent('beginInterceptingEvents');
 }
