Version: 51
OS: Windows

What steps will reproduce the problem?
(1) Connect to Windows using Remote desktop (I think it's important). I used Chrome Remote desktop, the curtain mode was off and the headphones connected directly to the Windows machine.
(2) Launch Narrator
(3) Open https://adrifelt.github.io/demos/page-info-demo.html

The permission bubble appears but it's ignored completely by the screen reader.
https://codereview.chromium.org/1067113002 claims that it's fixed. The problem is that BubbleDialogDelegateView::HandleVisibilityChanged never called because BubbleDialogDelegateView::OnWidgetVisibilityChanging isn't called. The root cause is in NativeWidgetAura. It triggers OnNativeWidgetVisibilityChanged but never OnNativeWidgetVisibilityChanging.
