All the a11y tests were failing for me with a window state diff
like this:
- state: active enabled resizable sensitive showing visible
+ state: enabled resizable sensitive showing visible
I guess the windows in the CI always gets the focus, but not when
I run it here. Generally focus seems asynchronous and hard to rely
on so I just made the test ignore the active state on toplevels.
The button now claims its menu as a child for a11y purposes,
which makes it possible for ATs to see it when the navigate
the tree top-down.
Update the a11y test to match.
