Piglins are angered when you open a chest minecart, despite this not having an animation or making a noise. This behavior is different from Java Edition, and since MC-172351 was resolved as WAI, it seems to me that the Bedrock behavior should be changed to match Java.

Steps to reproduce:
1. Spawn a piglin and a minecart with chest
2. While wearing at least one piece of gold armor, go into survival mode
3. Open the chest minecart in front of the piglin
-> The piglin will become angry and attack the player.

Note that destroying the chest minecart does not anger piglins.
