Android:QFiledialog doesn't show folders until path is explicitly specified.

On Android 6.0 or above QFileDialog only shows only inside app folder even if runtime permission is granted.(I used patch in QTBUG-50759)

QFileDialog::getExistingDirectory(NULL,"",QDir::homePath());

shows only /data under / and there's no way to select folder in sdcard.

but

QFileDialog::getExistingDirectory(NULL,"","/storage");

shows some folders including sdcard.
and if I go up to / , /data and /storage is shown.

The attached project demonstrates the behavior described above.
