Subject: [PATCH] Longpress overview in minimized mode only for resizable
 launches (1/2)

Since resizable launchers in minimized mode shows more of the docked
stack than in non-resizable launchers, it will play the same
functionality as split screen where long press overview button will
exit split screen into fullscreen mode.

Test: test was written - adb shell am instrument -w -e class

Fixes: 34892561
