New SELECT Popup: Compare OPTION style with the parent OPTGROUP.

New SELECT Popup: Compare OPTION style with the parent OPTGROUP.

When we serialize style data for an OPTION, we had a bug that the OPTION style
was compared to the SELECT style even though the OPTION is in an OPTGROUP.  We
should compare with the OPTGROUP style.
