Disc Bounce Never Generates in Mineshaft in Sulfur Caves

I have searched up to 20 minecarts with chests generated in sulfur caves, but not a single one contained the new music disc Bounce.

Steps to reproduce:

1. Create a world using seed -3003452031079375197.

2. Teleport to coordinates [-4791, -31, -736].

3. Open the nearby chest minecart and observe that no Bounce music disc has spawned.

4. Use Chunkbase(VeryUseful) to locate more chest minecarts of this type. Although they generate in sulfur caves, none of them successfully spawn the music disc.
