Reproduce:

1. In the water deep enough, place a magma block
2. Go above the downward bubble column quite high
3. Aim to magma block directly using downward bubble column and throw it
4. Aim to another block directly using still water and throw it again

Expected result: The trident moves faster in the downward bubble column

Observed result: The trident moves slower in the downward bubble column
