If you don't use the pick to break the iron door, you will find that the iron gate is still falling

This bug can be seen by many people that destroying the iron door with bare hands can also drop objects. As a matter of fact, a pick should be used to drop objects and not drop anything. After I saw Minecraft Wiki watching the destruction of the iron gate, I tried it. However, after the destruction of the iron gate, it can still fall off the iron gate, even the upper and lower parts will fall.

Steps to Reproduce:

1. first get the iron gate
2. into survival
3. after adjusting, do not destroy the iron gate with a pick.
4. after the destruction, pay attention to the drop of the iron gate
