That's so cute!this is the gif:
https://gyazo.com/a15f177a41ff03981efeedcd1cbd931c and this is it animating on the preview menu when you upload a new icon
You'd be surprised.... See, when i actually click his avatar... it's animated.... But listed as a jpeg.... This is where it's coming from and going into...so i looked into it and it depends on our image provider. this isn't something i can look into, but i will definitely add it to the suggestions!
