  Body: Hi
  in robotframework==6.0.2
  If arguments are given as shown on the screenshot, the values after list are not displayed in traces, but the values are processed and everything works.
  
  This is the line
  ```
      Combobox should have options             ${EMPTY}      Range 1    Range 2     convert_unit=ovca
  ```
