Only collapse bubbles when its from gesture nav

Test: atest BubblesTest NewNotifPipelineBubblesTest
Test: manual - force notification permission dialog to always show
             - open a bubble
             => it doesn't immediately collapse
             - swipe up on gesture nav
             => the bubble collapses
