I'm hitting the following assertion in a test suite after a RTS call:

        /*
         * Callers of this function set the cursor slot to an impossible value to check we don't try
         * and return on-page values when the update list should have been sufficient (which
         * happens, for example, if an update list was truncated, deleting the standard update
         * required by a previous modify update). Assert the case.
         */
        WT_ASSERT(session, cbt->slot != UINT32_MAX);

The suite is performing replication rollback in MongoDB. The assertion is happening on the _mdb_catalog table:
