Any time I've tried uploading them, they are converted to jpg files. The only way I've been able to include them is by referencing images that are already hosted somewhere.
I know that some instances have server-end logic in place to downscale uploaded images, or convert GIFs to WEBP, etc to reduce file size. I wouldn't be surprised if your instance just converts all GIFs to a static JPG for some reason.
