The game can log that a player is standing on air even when they're not

The logs of a server can include the message Player <PlayerName> standing on air - force-sending blocks below even when the player isn’t standing on air. I first experienced this moving normally around the world, but have gotten this to reliably work by spamming the space bar under a two block tall area in survival mode. It occurs every 10 seconds and happens regardless of the game mode of the player. This clutters the logs unnecessarily.

It also happens in the client logs when in a single player world.

Steps to reproduce:

1. Start a server and join it (or open a single player world)

2. Spam space in a two block tall space in survival mode.

3. Notice how the logs have the standing on air message every 10 seconds
