description: As we know, the player hitbox is and has always been 0.6 x 1.8. However, the vanilla bedrock server (incorrectly) tells the client that the hitbox width is 0.8 x 1.8. Interestingly enough, the local player does not understand this change, but it can be seen with all other players. Their shadow radius is bigger and toggling bounding boxes supports this notion. I confirmed this by reading the player's SynchedActorData and logging the packets clientside.

expected results: server tells the client that the player bounding box is 0.6x1.8
actual results: server tells the client that the player bounding box is 0.8x1.8
