Qt dependency removes /std:c++latest flag for msvc

{{CppApplication {
    // Depends { name: "Qt.core" }
    consoleApplication: true
    files: "main.cpp"cpp.cxxLanguageVersion: "c++20"
}}}

Above qbs file emits "/std:c++latest" option when compile main.cpp file.
In fact, the value of cpp.cxxLanguageVersion here doesn't matter because all strings except in ["c++17", "c++14", "c++11", "c++98"] will append "/std:c++latest" as you can see here: https://github.com/qbs/qbs/blob/master/share/qbs/modules/cpp/msvc.js#L96

However, if I uncomment "Qt.core" dependency, "/std:c+latest" flag disappears and I cannot use latest C+20 features.

FYI, `cpp.cxxLanguageVersion: "c+17"` works as expected with or without Qt dependency, although this is not an option for me because I need C+20 features.
