Actually, I can confirm that it does affect 20w28a

Hmm... It is very strange. I was playing and it didn't happen. I restarted my Minecraft and it happened then.

Can confirm in 20w51a.

Can confirm for 20w51a, although it may be intentional.

Can confirm in 21w06a.

Can confirm in 1.16.5 and 21w08b.

Can confirm in 1.17.

Can confirm in 1.17.1 Release Candidate 1. This is easily seen by causing intense amounts of server lag (for example, setting random tick speed to 100000) and placing/breaking a bed.

Can confirm in 1.17.1 Release Candidate 2.
