Entering a bed underground provides x-ray view for a split second

made a new world and didnt know this bug, i wanted to try another bug, which was in 1.61 Release Candidate 1, which was placing a bed infront of a skeleton the bed got destroyed.

but now to the point. i wanted to try the bug with the skeleton, and the placed the bed, just under the ocean and when i went to sleep i could see through the ocean which i think also can happen in caves.
