Brush can trigger auto‑placing blocks on touch‑crosshair control

When using touch‑crosshair control mode:

1. Equip the brush and press the attack button.

2. Switch to another inventory slot which contains blocks.

3. The game automatically keeps placing blocks continuously, it can even place blocks in mid‑air.

4. Press attack button again to stop this abnormal behavior.

This issue occurs in both Survival mode and Creative mode on the latest Minecraft Bedrock Edition.

Expected result

After attacking with the brush, no automatic block‑placing should happen when switching inventory slots. Player should manually trigger every block placement.

Actual result

After attacking with brush, switching to block slot triggers endless auto block‑placing, blocks can be placed on air. Press attack once more to stop.
