I have converted that elephant.png image to gif with apng2gif and uploaded the result here:


And I see the same behaviour than with the original png image [*].

So the bug seems related to animated images in general.

Can you reproduce this behaviour with the gif image on the Mac port?

[*] It seems there is something else also wrong, because I only see the gif image if I go to this index https://people.igalia.com/clopez/wkbug/170333/ and then click on the gif image. If I try to load the gif image directly or hit re-load once its loaded I don't see it (only a small square). But this seems an unrelated bug, perhaps related to the cache?. 
When the gif image loads it behaves like the apng one (like on the video)
