wm: Underp menu key release processing

Change Iacfedf711d43f6637023c87c00e6c6b8b8a437dc made key release perform
the assigned action regardless of alternate modes, but the keypress
processing depended on said modes. Make it consistent.

Revert "Reduce memory leaks by removing all views."

This reverts commit a61cab784f2560d972a1c30554a697d04993c57b.

This is causing BT icon to get caught up in "all views" removal. Backing this out until Clark can look into it.
