BatchedMesh.copy() fails with WebGL warning

[Ctrlmonster]

Description

Doing batchedMesh.copy(otherBatchMesh) results in a WebGL warning + nothing being rendered.
I saw that at least the _indirectTexture is not being copied inside copy(), but maybe something else is missing?

Reproduction steps

1. Create and render a BatchedMesh
2. Create a new one and call newBatch.copy(oldBatch)
3. Hide old one and add new to the scene

Code

const b = new BachedMesh(0, 0);
b.copy(otherBatchedMesh); 
scene.add(b); // <- will cause WebGL warning

Similar to #30961 (comment), the copy might be broken over time when the class has been enhanced with more features.
