Error encountered when cloning a BatchedMesh: Uncaught TypeError: this._matricesTexture.image.slice is not a function

Description

While attempting to clone a BatchedMesh, I encountered the following error: Uncaught TypeError: this._matricesTexture.image.slice is not a function.

I noticed that the BatchedMesh source code contains the following lines:

...
// Line 930
this._matricesTexture.image.data = this._matricesTexture.image.slice();
...
// Line 935
this._colorsTexture.image.data = this._colorsTexture.image.slice();
...

During debugging, I observed that the data property of image is a TypedArray, but image itself does not have a slice() method. I am wondering if image.slice() should be modified to image.data.slice()?

Since I didn't find the Image class in the Threejs documentation, I don't quite understand what the data structure of Image is, and whether only the Image in the DataTexture created in BatchedMesh does not have a slice() method

It’s good that you noticed, there really should be an image.data.slice() here to clone texture data.
