Put the summary of the bug you're having here
What I expected to happen was...:
I hit the wall and... that's it
What actually happened was...:
I go underneath even when the shift button wasn't physically touched
Steps to Reproduce:
1. make a platform of bottom slabs so that your Y coordinate is XX.5
2. place a roof above it so that there is a 1.5 block space
3. start ramming your body into it from weird angles. Going forward + strafing does it for me

the only thing consistent that happened in my survival and creative world was cobblestone slabs. I'll get some video of it but it seems kinda fishy without keystrokes

Actually, sometimes I go into full-on 1-block height when approaching such a gap from some angles. I'm unable to reproduce it, but it happens, and frequently, at that. Still need to test this myself for this week's snapshot

https://www.youtube.com/watch?v=kSvrLaKYZUY for evidence. It seems to be a pretty abstract bug, but I come across it pretty often in my skyblock world
Same issue as MC-177970.
I'm trying this right now myself but it doesn't seem to work, any specific blocks you used?
