Well, it might be this case sometimes but in the case when i was able to reproduce this issue it was null coming from native code so we were falling back to UIManager. I can enforce MRI creation even if size is correct - but again, the method signature does not promise the MRI in all cases so we might just modify the test case to not expect the MRI as granted even for the well-known files.
