[macOS] Quick Controls 2 ApplicationWindow does not offer fullscreen feature by default

It seems to be common practise for applications on macOS to offer fullscreen feature via the green button on the title bar. Quick Controls 2 ApplicationWindow does not follow this convention. The behavior also differs from that of Quick Controls 1 ApplicationWindow.

Steps to reproduce:

• Run the sample application attached on macOS.
• Observe how the green button works. Compare with other apps on macOS.
  EXPECTED: The behavior follows macOS app convention.
  ACTUAL: The behavior does not follow macOS app convention.

As a workaround you can explicitly set the flags needed:

ApplicationWindow {

flags: Qt.Window | Qt.WindowFullscreenButtonHint | Qt.WindowTitleHint | Qt.WindowSystemMenuHint | Qt.WindowMinMaxButtonsHint |            Qt.WindowCloseButtonHint | Qt.WindowFullscreenButtonHint

}
