Issue present for the past week or two on the latest and previous latest iOS versions. Likely unreliable to reproduce, but just experienced it here:

I tapped on the GIF, swiped down (… or up?) to close it, and the GIF zoomed in. From that point it’s difficult to close the GIF with one finger, but zooming out with two fingers works fine.
Same issue, happens fairly regularly with static images. Doing stuff in Procreate shows no similar issues with the touchscreen.
