The bug

MC-1133 was fixed in 23w18a, meaning end gateways are no longer counted under MC-122547. However, other methods remain which permit particles from end gateways blocks to be created by falling.

How to reproduce

Use the setblock command to get an isolated minecraft:end_gateway instance, then place a carpet on top or boat inside. Then fall on it from sufficiently high.

Expected results

For the carpet method, we'd get carpet particles. For the boat method, we'd either get no particles or the particles of the wood type the boat is made of.

Actual results

Obsidian particles.
