Visual bug when in a third-person block

I have found a bug that I think has been around for a while since they added the ability to enter block media or spaces of a block, it consists of if you put a staircase upside down and you enter as if it were an entrance and you change the perspective to third person, everything will go black when you are inside the space of the staircase you entered, in first person this visual bug does not occur, only in third person
