      The repro shows a query with $group (executed in SBE) and a $lookup (executed in document sources). When executed normally it shows queryFramework=classic, and when executed with explain it shows queryFramework=sbe.

      The QueryFramework enum for this query should be kSBEHybrid, meaning the queryFramework field in the slow query log should be "sbe"
