Aves plays that one in ~11s instead of ~9s.

I also noticed that some webp loop and some don't. Not sure where the responsibility lies, image or player.

Edit: added some Flutter issues with multi-frame decoding.

Should not worry about it. Webp sets loop times itself. Can be one time, can be several times, can be endless.
