[1.16.4] Changing player hitbox size doesn't center it on the player

[FlashHUN]

When I change the player's hitbox with EntityEvent.Size and recalculate it using Entity.recalculateSize() on both the client and server when it should change, the hitbox changes fine, however it is off-center and when the player moves they get teleported into the center of the hitbox.

 

EntityEvent.Size:

@SubscribeEvent
public void playerSize(EntityEvent.Size event) {
    if (event.getEntity().isAddedToWorld()) {
    	PlayerEntity player = (PlayerEntity)event.getEntity();
    	IPlayerCap cap = CapabilityUtil.getPlayerCap(player);
    	EntitySize changeTo = player.getSize(player.getPose());
    	if (cap.getSusanooActive()) {
    		changeTo = SUSANOO_CAGE;
    	}
    	event.setNewSize(changeTo);
    }
}

 

Entity.recalculateSize() gets called in the packet I sync the capability with when the data changes

 

Edit: the current fix I found for it is after calling recalculateSize() I need to set the bounding box again with

player.setBoundingBox(new AxisAlignedBB(player.getPosX()-(double)width/2, player.getPosY(), player.getPosZ()-(double)width/2, player.getPosX()+(double)width/2, player.getPosY()+(double)height, player.getPosZ()+(double)width/2));
