* 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);
```

atom/browser/native_window_views.cc
window_->CloseNow();
}
void NativeWindowViews::Focus(bool focus) {
  
  if (!IsVisible())
    return;
  if (focus) {
#if defined(OS_WIN)
    window_->Activate();
#elif defined(USE_X11)
    
    ::Window window = GetAcceleratedWidget();
    XDisplay* xdisplay = gfx::GetXDisplay();
    SendClientEvent(xdisplay, window, "_NET_ACTIVE_WINDOW");
    XMapRaised(xdisplay, window);
#endif
  } else {
    window_->Deactivate();
  }
}
bool NativeWindowViews::IsFocused() {
  return window_->IsActive();
}
void NativeWindowViews::Show() {
