"User banner" extension : image streched on card

Would there be a way to have it "cropped" on the picture of the user card as well ? uwu

Is it the Profile cover extension by SynchO?

I've never used it so I'm not sure but maybe the background-size needs to be changed to cover instead of 100% to prevent resizing? https://github.com/SychO9/flarum-profile-cover/blob/master/resources/less/forum.less
