Starting Spark profiler on Velocity causes packets to only send to Bedrock players when performing actions

[MiguVT]

Description

When the Spark profiler is started on the Velocity proxy, it causes packets to only send to Bedrock players when they are performing actions such as moving or punching. This results in a frozen state for players who are AFK, where they cannot see any updates or new entities.

Reproduction Steps

Start the Minecraft server with Velocity proxy and GeyserMC.
Ensure Spark profiler is installed.
Start the Spark profiler using the command sparkv profiler start.
Join the server as a Bedrock player.
Stay AFK without moving or performing any actions.
Observe that no packets are received, and the game appears frozen.
Perform any action (move, punch, etc.) and observe packets being received again.

Expected Behaviour

Bedrock players should continue to receive packets and game updates even when they are AFK and not performing any actions.
