Error when importing VRM 0.x: "Destroy may not be called from edit mode! Use DestroyImmediate instead."

[eternal]

I'm getting several instances of the following error when I import a VRM 0.x file.

Destroy may not be called from edit mode! Use DestroyImmediate instead.
Destroying an object in edit mode destroys it permanently.

This is after copying your version of MaterialFactory.cs into the appropriate folder, of course. I would try this with VRM 1.0 if I could, but I'm hitting an error when migrating from 0.x to 1.0, and I think that's unrelated to this asset.

Current versions:
Unity 2022.3.6
UniVRM-0.115.0_7e05.unitypackage
VRM-0.115.0_7e05.unitypackage
SimpleURPToonLitOutlineExample_for0.108.0.unitypackage

Interestingly, the error doesn't seem to break the import process at all - I can still drag the resulting prefab into the scene, and it seems to work correctly.
