Currently the dismiss button just pops in once the animation is complete, which is somewhat jarring (and because the animation decelerates as it ends, it feels like there's a delay before the button actually appears). This change starts fading in the button while the animation is happening, matching its location to the preview at each animation update. Bug: 155415756 Fix: 155415756 Test: manual -- tested with ltr/rtl, portrait/landscape, and from overview vs keychord, all looked correct Change-Id: Ibd3ea2a4127d6fee87ec9b73d73f8f5a184d1417
