This affects all browsers and not just Chrome, as the media falsely reported it. Mozilla just rolled out a fix, and Brave is looking into it. This bug is likely related to the "zero-click" iOS 0day that was reported by Citizenlab last week.

There is optimization. Every frame in the gif can define a rectangle it’s drawn in on top of the previous image. This works fine for reduced color animations (like cartoons), but of course breaks completely for videos.
