@hig/Dropdown: The values in the text field are only displayed as a string (not as a react node)

Hi team,
On the next example (image below) when I use the `renderOption` prop and then I create a span element inside it. When I open the list element, that is rendered as expected, but when I set the `value` prop, the textfield only display the string value(omit the span element)


Begin with the @hig/Dropdown implementation and reproduce the renderOption/value example from the issue; no source file or test is named in the report. Trace how the selected value is displayed, then add or update relevant coverage so the selected field preserves the rendered span while the option list remains correct.
