Hello,
i found a bug. If you hit the block with any sword, that has the Modifier "attackspeed" at about 40 or more you can not move in any direction for a few ms. But if you are doing it really fast by using a Speedclicker at around 40 clicks per second the movement and even the gravity stops working. This bug works only in creative mode. I'll send a video showing the bug with and without speedclicker.

Cannot reproduce in 1.20.1. Seems to have been fixed along side MC-157436.
This applies to tridents too. Nice to see someone finally reported this because I always forgot to. You can really see the stuttering when sprint-jumping in a direction, even without high cps and just holding left click.
