GIF as profile picture

Expected behavior

Possibility to select a GIF as profile picture.
But the animation should not appear until the image is enlarged.

Actual behavior

You can choose GIFs as profile picture, but no animation is displayed.

Explanation

I think that would be a nice little feature that doesn’t exist in any other messenger.
For example, it would then be possible to wave at your own contacts in the profile picture if they tap or click on it. A bit like Apple’s Live Photos.
