Not a bug Uploading multiple GIFs one by one in XFRM

Replicated here, making a resource:

The first GIF is animated, the following two aren't, but uploaded as seen in the attachments here.

XF as well if 1 or more is uploaded at a time.

This is because the first image is smaller than the resize threshold (1280px) so we just use it as-is. The other two are resized, and GD does not support animated GIFs. You can use Imagick on your own site if you require support for resizing images with animation.
