Hillbilly gragas' hat disappears in bushes

I've already used the PBE report a bug system and I've also done another post maybe about a month ago but it still isnt patched. It doesnt change gameplay but at the same time it should be very easily patched. Hillbilly Gragas' hat gets removed when he goes into a bush. Thats it, I know but it still is kind of weird seeing his bald head.

Thank you for reading this and I hope it gets patched soon.
