Player feet is clippinng inside blocks when crounching

Hello i have seen this bug happening for a while now i have not been able to find bug report about it yet so very sorry if it’s duplicate of one.. Shortly player model is put inside of block when crouching.. But anyways here is how to reproduce it:

• 1) Join any minecraft world (doesn’t metter if it’s server or singleplayer) [unless the server uses older version crouching]

• 2) Stand on any minecraft block perfectly leaves becouse you can see thru them

• 3)Crouch (shift) and press F5 to see yourself
  Expected result: Player model wouldn’t be clipping into the ground when crouching
  actual result: player model clips into the ground when crouching
