In case where a method- and property name overlap, using the method is less unambiguous than I thought - mozjs52-based gjs will only see the method, while mozjs38-based gjs will only see the property. We are in luck though, and the real property name contains dashes that allow us to refer to the property in a way that works for all gjs versions. https://bugzilla.gnome.org/show_bug.cgi?id=785090
