Microsoft Graph - Children Navigation Property Not Working for Reused Term Store Terms

Question

I am running into several issues that are making it very difficult to use Microsoft Graph for terms that are reused:

If a term is reused, calling /children on its parent only returns it at its source location

• graphClient.Sites[site.Id].TermStore.Groups[groupA.Id.].Sets[setA.Id)].Children returns Term A
• graphClient.Sites[site.Id].TermStore.Groups[groupA.Id.].Sets[setB.Id)].Children returns nothing.
• How can I user Microsoft Graph to discover that Term C even exists?

If a term is reused, calling /children on the reused term returns all of its children regardless of parent (This issue is described here also https://github.com/microsoftgraph/microsoft-graph-docs/issues/14905)

• graphClient.Sites[site.Id].TermStore.Groups[groupA.Id.].Sets[setA.Id)].Terms[termA.Id].Children returns Term A AND Term B!
• graphClient.Sites[site.Id].TermStore.Groups[groupB.Id.].Sets[setB.Id)].Terms[termA.Id].Children returns Term A AND Term B!
• How can I retrieve only the desired children?

Example Term Store - This works as expected in the Term Store admin page

• Group A
  • Set A
    • Term A (Source)
      • Term B
• Group B
  • Set B
    • Term A (Reused)
      • Term C

Is Microsoft going to fix this in Microsoft Graph, or should I stop reusing terms?

Has this been resolved (November 2024) because here's what I get using MSGraph API (latest version):

Children of the set or term where the term is reused DOES NOT return the reused term.

graphClient.Sites[siteID].TermStore.Sets[setID].Children.GetAsync();

and

graphClient.Sites[siteID].TermStore.Sets[setID].Terms[termID].Children.GetAsync();

In the relationships - there is never any FromTerm or ToTerm objects:

graphClient.Sites[siteID].TermStore.Sets[setID].Terms[termID].Relations.GetAsync();

Is this still in development?

Thanks
