Issue still occurs in 1.16.100.52.

It seems that when you crouch while the game is attempting to place a block it'll break the "block chain" (a quirk where block placing is locked into a straight line after placing 2 blocks - MCPE-30610)

It seems to have a affected range relative to the players y position.

I have noticed this on Minecraft: Education Edition as well, but it just makes it faster to build when you fall so for the "Block Placing Without Crouching", it isn't a bug for me.

you can do this while standing still, and you can do it in survival, without flight.
How to reproduce:
1. Get some blocks, and look at the ground in front of you
2. Hold down the jump and crouch buttons
3. Hold down the place button
4. You will continue to place blocks, even when you shouldn't be able to. Max height for survival is 10, creative doesn't seem to have a height limit.
Is this an issue in the latest beta version?

Affects 1.17.2

Affects 1.17.11

Affects 1.18.1

Comfirmed it does work

i don't know about flying but the swift sneak enchantment causes crazy block placement when you use it while building. Places blocks below blocks if you are bridging out, or above them if otherwise.

Blocks erroneously pillar vertically while walking backwards and placing with Swift Sneak III active.
Confirmed, affects 1.19.10, regardless of fly mode.
Steps to Reproduce
Equip Swift Sneak III Leggings of any type.
Select any full block.
Input command /gamemode s
Toggle/hold crouch button.
Walk backwards while holding the place block button.

You can also pillar blocks up through other blocks with swift sneak and crouching while moving horizontally, a vertical pillar can be piled up through other blocks with this.

Right click to place a block while moving on a snow layer will place the block in the wrong position too
Thank you for your report!
