Error when upscaling GIF

[makew0rld]

I’m trying to 2x upscale a 25 frames 800x800 gif but it says imagine [image] block is out of bounds.

This bug comes from the gif library, specifically this line. Why is it triggering in this case?

Animated GIFs are not supported as input. When I try some basic things with an animated GIF (including upscaling), I don't get the error. It works, just that only the first frame of the input GIF is processed.
