Setting any floating block to a pointed dripstone, causes the replaced block to drop as an item.
Steps to Reproduce:
1. Run the command /setblock ~3 ~1 ~ andesite
2. Run the command /setblock ~3 ~1 ~ pointed_dripstone
3. Upon the andesite being replaced, it will drop as an item.
The block that is replaced drops as an item.
The block that has been replaced should not drop as an item, as no other blocks being replaced follow this pattern.
I have attached a video which shows this bug in action.
