Window doesn't close with `close` event handler and window.close()

NWJS Version : 0.58.0 Operating System : Windows 10

Expected behavior

When a window uses window.close(), handling of the close event should behave the same as if nw.Window.get().close() was called or the user manually closed the window.

Actual behavior

If window.close() is used to close a window, an event handler cannot be attached to the close event. If an event is attached, the window does not actually close when win.close(true) is called.

How to reproduce

1. Open NW.js SDK and open the DevTools console.
2. Execute:

nw.Window.get().on('close', function() {
  this.close(true);
});

1. Execute:

window.close();

1. Note that the window does not close. However, the user can no longer interact with the window.
