avif-sequence files not rendered properly
I have tried opening a avif-sequence file (gif style animated image) in gThumb 3.12.2 on Fedora 37. It appears to only display the first frame of the sequence. A static heif image is rendered correctly.
Here is the information provided by heif-info for the problematic file:
