Can you tell me whether this is an application bug or possibly a bug with the Spur VMs weak collections? I'd hate for this to be an undiagnosed and unfixed VM bug.

Much more likely an application bug. Copying Morphs that contain Rubric editors is non-trivial.

Yes. I am sure it can't be VM issue. My candidate for leak is spotter windows history. I remember I detect some leaks when it was integrated in Pharo7. But I was not sure, it was very fast test. And it can be wrong.
