Bug: document not saved with "save as" and subsequent "save", broken links

[BananaJuiceNomNom]

Create a document, say a screw, insert linked parts, say a nut, save the document as "A". Then implement changes, e.g. other user parameters like thread length of the screw, use "save as", name it "B" for a hard fork. We assume "save as" creates an entirely different document, not linked to "A". This is not the case, and Fusion does not seem to use the file name but a hidden ID. The critical bug here is that this ID is not changed when a copy is saved. 

Here are two examples for inevitable chaos 🙂
1. The lost connection: Open any file that had A linked. It might have B linked now. Or not. Either way, it shows a broken link, which can't be fixed.
2. The impossible circle : In the document B, insert A via link. Save file.

This seems to be related to the FUS-45957. I just discovered a 2min older thread where Karin mentioned save as as broken and filed under the internal bug "FUS-45957".
