Powdered Snow creating extra particles

If you are in a minecart in/directly under powdered snow that is not on a rail and press a movement key, the particles that come off of powdered snow when moving activates even though you aren't moving.

Steps to Reproduce: (from MC-220465 by [Mod] Avoma)

• Place a rail.
• Place some powder snow above it.
• Place a minecart onto the rail.
• Destroy the rail.
• Get inside the minecart.
• Move forward.
  → Notice how particles are produced, despite yourself not moving at all.
