Thank you for your submission!

It's challenging to fully understand the issue without more examples and detailed comments. However, from my analysis, the issue appears to originate from mongomock rather than mongomock_motor. As such, I believe addressing this problem here would not be appropriate. Instead, it should be resolved upstream in mongomock. Can you create an issue there if my assessment is correct?

While the issue remains unresolved in mongomock, you could consider using a fork or applying a monkey patch in your test code as a temporary workaround.

For reference, here are the relevant implementations:

• mongomock's implementation
• motor's implementation

Please let me know if you need further clarification or assistance.
