macOS app quits after closing first frame on sciter 5

On macOS, if I attempt to start a second frame, after closing the first one, the entire program quits.
But on Windows, the second frame appears right after closing the first.

Quoting Andrew

For some reasons, this:

let mut frame = sciter::Window::new();

Creates sciter's window with SW_MAIN flag.

Closing main window causes [NSApp stop:nil] call. Seems like Cocoa cannot restart shared application (NSApp). Or even quits from main before that.

Solution is to start main window in hidden state, create secondary window from script and show main after secondary closure.
