Keeping the same node version (for example v0.10.21), suddenly the constructor name changed for the Cursor class. What caused this change?

Is such a change suitable for a patch release (1.3.19 to 1.3.20)

In our case this breaks the functionality that relies on the fact that a find operation result was of type constructor. We check it using: result.constructor.name (we want to avoid "instance Cursor")
