gtk_widget_reset_rc_styles() is for all practical purposes
an internal function, so it doesn't need to behave in easy-to-use
ways. And the popup for the combo is a separate toplevel so it
should and doesn't get affected by gtk_widget_reset_rc_styles().

Reloading only the styles of some widgets in your app isn't
supported. To reload RC files for all windows in your app,
look at the code in testgtk.c ... its a bit ugly code, but
its not (IMO) a common operation, so I'm not that concerned
by it.
