Although we cannot really show anything but application modal
dialogs on iOS, falling back to using non-native dialogs for
window modal seems unnecessary strict; In practice you will
never have a work flow on iOS where you have several windows
visible, and at the same time, need to show a dialog that
blocks only one of them.
This patch will lift the restriction, and handle window modal
as application modal on iOS.
