Anvil that falls destroys other falling blocks

To recreate the bug u must put an falling block(like sand or even an anvil) and on top of it an anvil. If they fall for more then 2 blocks and end up on something that will make them pop(like carpet) only the anvil will pop and the other entity will disappear .

 

Here's a video of me recreating it: https://youtu.be/4salGay0Z3M
