The bug
The player shakes up and down if it uses a slow falling potion while having the slow falling effect.
The jittering can be stopped by sneaking.
To reproduce
Place a slime block
Get the slow falling effect
Jump while on top of the slime block
→ ❌ When landing, the player will jitter

I was able to reproduce this.
I did some tests to make sure that it isn't any specific Slow Falling potion doing this. It's doing it for all of them.
Potion of Slow Falling (1:30)
Potion of Slow Falling (4:00)
Splash Potion of Slow Falling (1:30)
Splash Potion of Slow Falling (4:00)
Lingering Potion of Slow Falling (0:20)
Lingering Potion of Slow Falling (1:00)
Can confirm in 1.20.5 Pre-Release 1.
Considering the original poster has been inactive since 2019, I would like to request ownership of this issue. Though, I am understanding if that's not necessary considering the issue has been fairly kept up with on the affected versions.
