System Look and Feel option should be using system theme highlighting colors
Description
In Windows "System Look and Feel" option has different colors for the main Spark menu options highlighting (when one is hovering mouse pointer over the menu option). It looks like Spark is using light blue highlight color for the original older menu options, and all the new menu options have dark blue (depends on Windows current theme - classic in this case) highlighting. It's seems logical to stick with the current system theme, so in this case all highlighting should be dark blue or depend on the system theme.
