Location mapview example incorrectly says ssl support is missing on WebAssembly target

When running the Location / Mapview example on WebAssembly target using a map accessible via https (which is required for WebAssembly), a large text message is overlaid over the map saying:

The active map type requires (missing) SSL support

Even though it works.

The problem seems to come from the following code in main.cpp:

#if QT_CONFIG(ssl)
    engine.rootContext()->setContextProperty("supportsSsl", QSslSocket::supportsSsl());
#else
    engine.rootContext()->setContextProperty("supportsSsl", false);
#endif

QT_CONFIG(ssl) is not defined for WebAssembly target. However, the browser can still download via https.

Changing it to something like:

#if QT_CONFIG(ssl)
    engine.rootContext()->setContextProperty("supportsSsl", QSslSocket::supportsSsl());
#elif defined(__EMSCRIPTEN__)
    engine.rootContext()->setContextProperty("supportsSsl", true);
#else
    engine.rootContext()->setContextProperty("supportsSsl", false);
#endif

fixes it, although perhaps not ideal fix.

Note that to get Location to work on WebAssembly, you need to apply the fix in https://bugreports.qt.io/browse/QTBUG-125248
