I think there's no issue to investigate, as far as I can see that's what the "Open With..." button does, it returns Open and doesn't set any selectedService, it's the caller responsability to act on that. For example https://lxr.kde.org/source/network/konqueror/src/urlloader.cpp#0266 Maybe it's a documentation problem that should make it clearer that is what the OpenWith button does?
