Let me take a look.

a tray->ActivateBubble() call before test_item_2->detailed_view()->FocusTitleRow() will fix this. I will merge the fix into the CL in 621791.

This is actually a functional regression in material design. I'm working on a CL to fix this now.

[Ash MD] Restore focus on detailed row when exiting detailed view

For Ash material design (--ash-md=experimental), restore
focus to the previously-focused system menu row
when transitioning away from a detailed view using
the keyboard (i.e., when the back button has focus and
the return key is pressed).

Do not give instant focus if a view's toplevelwidget is not active

If the top level widget isn't active during setting focus view, we store the focused view and then attempt to activate the widget. If activation succeeds view will be focused. If activation fails |view| will be focused the next time the widget is made active.

Based on this rule, a set of unittests related are modified.

This is a following up CL for 2113163002 as there are already too many patches there.
