- When the change to finish activities was made in ag/2067154, it exposed
an issue in pinned stacks where we would resume the next top activity
once the top activity finished pausing. Normally, the pinned stack is
not focusable, but since it has an alwaysFocusable menu activity it
becomes the focused stack and falls into this case.
Instead of finding the next top activity, we need to find the next top
focusable activity to resume, and fall through to focusing the top
activity in the next focusable stack if there is none.
