System locale (returned by QLocale::system()) always returns Qt::LeftToRight for QLocale::textDirection

Set a RTL locale in Windows. Get a system locale by QLocale::system(). Get textDirection value - it will be Qt::LeftToRight, no matter of actual direction.

QLocale::textDirection implementation uses a switch on QLocale::Script. QLocale::system().script() returns QLocale::AnyScript.

Checked on Windows only, but looks like it will be the same for other platforms.

Workaround: create another QLocale object using language and country of system locale. It will set script to proper value and return correct text direction.
