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.

Might be intended due to one of the changes in 1.16.2 pre-release 1:
Piglins now become angry with players who open or destroy a Chest Minecart
I tested on every platform and it happened too. Platforms should be changed to multiple.
