      Description

      There was a test failure from automated stress testing indicating that an unexpected key order was seen during cursor traversal.

      Here's the signature:

      Checking out Revision 35197670742f242aada9b5d43620e7a1f9d1f0e8 (refs/remotes/origin/develop)
      

      The failure reports:

        60: table, variable-length column-store (2 seconds)
      t, file:wt, WT_CURSOR.prev: WT_CURSOR.prev out-of-order returns: returned key 94544 then key 94567: Invalid argument
      

      The test/format configuration that triggered the failure is:
