I don't think this has been reported, but due to the new change to not crouch when flying in creative mode, when touching the ground it isn't possible to crouch, even if you're actually walking slower.
Steps to Reproduce:
Go in Creative mode.
Start flying.
Press your crouch key to descend until you touch the ground.
Press your crouch key again while on the ground (you can try walking to see how the speed decreases).
Observed Results:
The character isn't crouching even if it's on the ground.
Expected Results:
The character is crouching because it's on the ground.
In java, the player automatically turns off the flight mode when touching blocks, unlike bedrock. It seems to me that bedrock behavior is much more convenient (at least for me). If the player crouches with the flight mode turned on, this can again cause problems with passing through the blocks.
Perhaps this behavior can be resolved as WAI.
