This works in real life as well. Even in host doesn't follow the
above rule, it will work if you do it in plugin:

Plugin()
{
GetGWorld(&savedPort, &savedDevice);
SetGWorld(pluginWindow, NULL);
...
if (ok pressed) DisposeWindow(pluginWindow);
SetGWorld(&savedPort, &savedDevice);
}

Do not blindly follow any directives regardless of the source.
