Additional Notes

This function is essentially an alias for navigator.serviceWorker.controller.postMessage(data), but it also checks if Service Worker is supported and if there is currently a controller, so it is safe to use anywhere.

Remember: Using shift+reload bypasses the service worker so the window will not be controlled! This prevents messages from being posted!
