* Electron version: 1.4.6
* Operating system: Windows 10

### Expected behavior

After minimizing the window it should restore to the same size.

### Actual behavior

After minimizing the window it is restored to a larger width.

### How to reproduce

The issue started with Electron 1.4.5 and will only appear when you use `minWidth` property in browser window config. As an example:

```javascript
const windowConfig = {
	title: "Test app",
	width: 800,
	height: 600,
	minWidth: 800
};

const mainWindow = new BrowserWindow(windowConfig);
```

return new NativeWindowClientView(widget, this);
}
views::NonClientFrameView* NativeWindowViews::CreateNonClientFrameView(
    views::Widget* widget) {
#if defined(OS_WIN)
  WinFrameView* frame_view = new WinFrameView;
  frame_view->Init(this, widget);
  return frame_view;
#else
  if (has_frame()) {
    return new NativeFrameView(this, widget);
  } else {
    FramelessView* frame_view = new FramelessView;
    frame_view->Init(this, widget);
    return frame_view;
  }
#endif
}
