in some cases .components gets left on after dereffing and is causing me issues

[shanejonas]

Describe the bug
When trying to use the result of parseOpenRPCDocument, its leaving remnants of the dereffer left over. specifically in this case .items is left with .components still there.

this leads to circular references and lots of pain for the developer.

heres a minimum doc that does it for me:
