Only in 1.19, it seems now Bee cannot exit or enter a beehive if an open face has a carpet in front. 

I discovered this in my bee farm where I had only the top and front of the beehive exposed, and in front I had a carpet covering a hopper. I assume the top has never been an accessible face, only the sides? Bees could enter/exit with the carpet present in 1.18. Since upgrading to 1.19 this is no longer the case.

Unsure if this was intentional? Seemed like a bug. I would not expect a carpet to block the face of the hive in this way. Screenshot of working setup, moss carpet was placed over this exposed hopper (for aesthetics).
