The bug
The fix for MC-262424 is effective so long as the layer remains grounded while sprinting. However, when sprint-jumping against the edges of blocks, where some non-full block is on the other side of this edge, it remains possible for an occasional particle of that block to be generated in midair despite the player not colliding with it.
How to reproduce
Create a setup as depicted
Sprint-jump across this gap (you can use F3 to align your angle if required)
Observe
Expected results
No particles of the carpet block you're not colliding with would be produced.
Actual results
There is the occasional particle produced upon reestablishing contact with the ground, generated in what is effectively midaur.

Cannot reproduce in 1.20 pre release 5. I've tried to align my camera at a perfect 90 degrees angle with a tp command but still cannot reproduce.

Follow up: I've used yellow wool blocks instead of the carpet in my tests, and I've since reproduced this bug with carpets. It only happens when sprint jumping as described. Did you use carpets in your testing too?

Yes, the report used carpets (you can tell because it sticks out slightly over the grass blocks in the overview image).
