Notification Presentation Animation Glitch

Once in a while, presenting a notification will show the notification for a split second on the screen before it disappears and the animation brings the notification up. Using ```modalPresentationStyle = .overFullScreen``` made the glitch appear much less, but not permanently. A current possible win-win solution would be having a custom animation designed so that notification presentation looks nicer and we avoid using the glitchy presentation.

There is no known way to consistently replicate this glitch besides opening notifications constantly and, thus, no video is currently available.

Start by repeatedly opening notifications to observe the intermittent flash, then inspect the notification presentation flow and the modalPresentationStyle = .overFullScreen workaround mentioned in the report. No file or test is identified; done means the notification no longer briefly appears before its presentation animation and the resulting animation is visually smooth.
