Medieval Gate no longer opens and there is a hole in the ground!

after the Minecraft update 1.16.0.63.
The blocks that move like sand, red sand, gravel and concrete dust (all colors) after being punched up with pistons will now come item and before they fell as a block
  This prevents a gate that opens vertically and closes because the sand rises and pushes the blocks that are solid to open when the sand goes down it should stay as a block for the next time that the door would be opened more in this version it becomes an item when it hits the ground! This should be fixed soon!
