While I was creating piston laucher for my nether farm i noticed some dirt particles on honey block while there's items above it. Well, this is just a visual bug and it doesn't affect the gameplay. this bug I found is from 1.17.2 but there's no option to select on the Affecte Version/s tab

Steps to reproduce:
1. Create a redstone clock to rapidly extend and retract the honey block (make sure that there is no opening for the items to escape except the top of the honey block
2. And drop some item from the top of the honey block and its done.
