The bug
When the center of the player is not above scaffolding, they are not experiencing its ladder effect: Smoothly going up and down.
Instead they jump up one scaffolding block at a time and fall down multiple scaffolding blocks when going down.
This is related to MC-1133, but possibly not a duplicate, because some functionality (that you can go up and down) works as expected.
How to reproduce
Build a tower of scaffolding
Move partially inside it, but make sure that your center is not inside it
Move upwards by pressing the jump key
→ ❌ You jump up one block at a time instead of going upwards smoothlyMove downwards by pressing the sneak key
→ ❌ You fall downwards

Reopend and only marked as related to MC-1133 since some functionality (going up and down) works as expected.

Does that mean it's unfixable?
This bug is annoying. (using google translate)

Can confirm in 1.20 Pre-release 6

Can confirm in 1.20.2 and 23w42a.
This bug is "very important". I fell to my death many times due to this. Mojang should rethink its priorities(using google translate)

This is a bug that many people encounter.

Confirmed in 1.21.3
