patch 9.1.1403: expansion of 'tabpanelopt' value adds wrong values

Problem:  expansion of 'tabpanelopt' value adds wrong values
          (Shane-XB-Qian, after v9.1.1391)
Solution: update tabpanelopt expansion function and expand only valid
          values (Hirohito Higashi)

related: #17263
closes: #17359
