Put the summary of the bug you're having here

What I expected to happen was...:
When sneaking just after sprinting, the block particles from sprinting should dissapear

What actually happened was...:
Particles coming from the ground (block particles) from sprinting still appear when sneaking just after sprinting (these particles should disappear, as they do when you stop sprinting to normal walk, but not from sprinting to sneaking)

Steps to Reproduce:
1. Start running with your sprint key (left Ctrl for me along with W to move forward)
2. Release the sprint key (Ctrl) put keep going forward, you will still be sprinting
3. Press your sneaking key while still having a finger on W, you will start sneaking while still going forward

4. Press F5 to be in third person view, particles should appear while you're sneaking while going forward
