Class not getting passed through get_avatar

Hey there, it looks like y’all aren’t passing along args from get_avatar from what I can see in the class-wp-user-avatar-functions.php, which is causing my profile photo to not get it’s class applied, which in turn makes it oval-y.

I know there are work arounds (add some css for the avatar class). But I maintain several themes and having to go around fixing this every few months someone picks one out is an issue for me. Is it super hard to fix? if so I totally get it, but if not I’d super appreciate getting those args across.

Thanks a million!
