Powder snow triggers different events depending on where it is placed

The bug

When a powder snow bucket is used on a cauldron, or when a cauldron is filled with powder snow from a snowstorm, it uses the fluid placed event. When it is placed on the ground, it uses the block placed event.

This can be tested by removing the fluid placed event from the vibrations tag. Now, placing powder snow in a cauldron will not trigger sculk sensors, while placing it on the ground will.
