When using the playerBreakBlock event in Minecraft Bedrock's GameTest framework, cancelling the event (event.cancel = true) on a renamed chest causes the chest's custom name to reset, effectively erasing the custom name after the event is canceled.

• Rename a chest using an anvil.
• Implement a GameTest script that listens for the playerBreakBlock event on the chest.
• In the event handler, use event.cancel = true to prevent the chest from breaking.
• Attempt to break the renamed chest in-game.
• Check the chest's name after the event is canceled.
