      Before 20w27a, when you were sneaking you could always step off of blocks with a jump if you had a block above, and the block below had air next to it. But due to the fix of MC-2404 this has led to a case where this is no longer possible. The behavior now seems to be like if sneaking applies an "invisible barrier" on you that has some side-effects with knockback resistance or status effects (See MC-200282 & MC-199326), which in this case is jumping.

      While it doesn't seem to be a very noticeable issue at first, when you are underground going around closed spaces or diagonal stairs it is very problematic due to how this mechanic was critical when you were hiding from players in this kind of situations. And also, this makes sculk sensor detections being unavoidable on closed spaces, like caves.

      In a clip of Minecraft Live 2020 where the deep dark was showcased, this bug is noticeable when the player is trying to sneak around the sculk sensors at some point.

      How to reproduce:

      1. Create a void world.
      2. Place a block under and above you (see attachment).
      3. Try to get out while sneaking and jumping at the same time.
      4. You can't.
