It’s intentional.
It’s like when you are in your cabin and need to get some wood or snow (to use as water) outside.
Merry Christmas!
I understand. Thanks, AOU.
A while ago, having hardware acceleration enabled in my browser had my super old GPU going nuts from the snow effect and the animated holiday poal logos, so I had disabled/blocked them. I've since upgraded my GPU and it isn't a problem anymore.
Seeing the snow suddenly on some pages reminded me I had it disabled and I thought it was a bug.
Merry Christmas to you as well!
