This issue was fixed in 22w03a, possibly along side the fix for MC-243015. (though that second part is more speculation, as it was just the issue most closely related to this one which was fixed in that snapshot)
Here is a side-by-side demonstration (if the stuttering is not observable from the video, you may need to test on your own):

Can confirm for both 1.15.2 and 20w21a, the block does jump up a little bit indeed.
