When placing a block, if a mob walks directly into it as it’s being placed, the block is broken. However, the broken block vanishes and cannot be picked up. It is necessary to exit the game and log back in, at which point the broken block will now be in your inventory. I have seen this since at least version 1.21.
Environment
Specifically noticed when placing workstations near villagers
