      Steps to Reproduce

      run the following js in mongosh and watch result:

      b = 'lt'

      switch (b) { casecase : print('gt'); break; case 'lt': print('lt'); break; case 'le': print('le'); break;}

      b = 'gt'

      switch (b) { case 'gt': print('gt'); break; case 'lt': print('lt'); break; case 'le': print('le'); break;}

      b = 'le'

      switch (b) { case 'gt': print('gt'); break; case 'lt': print('lt'); break; case 'le': print('le'); break;}

      Expected Results

      The three switch statements should print 'lt', 'gt', and 'le' respectively

      Actual Results

      the first switch statement print:

      lt
      le

       

      the 2nd switch statement print:

      gt
      lt
      le

       

      the 3rd print:

      le
