Move email with static graph ID for email results in duplication of emails

Describe the bug

Using the move mail endpoint with immutable graph ids for mail creates duplicate mails

    headers = HeadersCollection()
    headers.add("Prefer", 'IdType="ImmutableId"')

was used to get the immutable graph id

1. Place email in test inbox ("Invoice processor test inbox"):
   

2. Move email manually in OWA to another folder ("Invoice processor test cannot process")
   

3. Call the move email endpoint to move email to ("Invoice processor test done"):
   Email is moved out of inbox ("Invoice processor test inbox"):
   
   Test emails moves to target folder ("Invoice processor test done")
   
   Test email unexpectedly also stays in ("Invoice processor test cannot process")
   

I now have a duplicate of the email. This should not happen if you call move on a email right? Is this intended behavior because of the use of immutable graph IDs or is this a bug?

Expected behavior

Email should be moved not duplicated

Start with the move mail endpoint and the immutable Graph ID request shown in the report. Reproduce the sequence using SDK 1.12.0, then compare it with the documented non-static ID workaround to determine whether duplication originates in the SDK or the Graph service. Done means identifying the cause and documenting or testing a fix for moving without duplication.
