Describe the feature

Actually I’m not sure if it’s unrelated to third party extensions, since it’s such an uncommon thing. The GIF in Omniscient Reader’s Viewpoint cover from FlameScans isn’t running.

Feature Motivation

Since the hosts went to the effort of getting or even creating a GIF for a cover, it’d be cool to display it. Not a dealbreaker though.

Anything Else?
