    Description

      Memory tracking underflow can also happen here:

      https://github.com/mongodb/mongo/blob/e7544180078415f6dd6bce44b90033f2599abf52/src/mongo/db/pipeline/memory_usage_tracker.h#L157

      Previously this place is patched to prevent the underflow from happening:

      https://github.com/mongodb/mongo/blob/e7544180078415f6dd6bce44b90033f2599abf52/src/mongo/db/pipeline/memory_usage_tracker.h#L54

      The same fix should be applied to the first location as well.
