Done! This was fun 🙂

I could change the description of this bug to reflect my current understanding of it (and to better describe the bug), but I thought I'd ask if that's what you want here first. Should I update the description?

I found an even easier way of doing it! Video uploaded (named "Ice Sneaking Direction Glitch Take 3") 🙂

Your wiggles when crouching should be shorter (change direction with the same frequency as before crouching). Also, your horizontal mouse movement (which you may need to attempt a few times until the glitch happens) should be a bit longer. The purpose of this movement is to change the direction you are facing to be nearly (but not exactly) in line with the axis, so assuming you start facing perfectly diagonal, the change in the direction you are facing because of this movement can be up to 40 degrees.

I hope this helps 🙂

New video demonstrating the glitch uploaded for 1.16.4

Yes, and I found an easier way to replicate it. I'll attach a new video later today.

Done.

As you can see, when I sneak along, pressing only a or d, I go parallel to the blocks rather than diagonally. Then when I step onto the netherack, my direction changes to what it should be and I start moving diagonally.
