Fix split screen divider corners flicker
Divider bar might be hidden before swipe-up gesture started when users
touching task bar region. This makes sure to update visibility of
divider bar only after gesture started.
Fix: 219995626
Test: long press task bar region to stash/unstash task bar, divider bar
won't be hidden as long as it didn't trigger swipe up gesture.
