QDir::Filter::Executable has no effect with QFileDialog

When QFileDialog is used with filter QDir::Executable or other option like QDir::Files , QFileDialog does not honor any of these filter.

This does work when named Filter is used. But to make it across all platform options like QDir::Files QDir::Executabl etc is what is supposed to use.

Attached little code shows it:

QFileDialog dialog;
dialog.setFilter(QDir::Filter::Executable);
dialog.exec();
