* It includes a script in the page * It uses a callback to ensure any code dependent on the include runs afterwards * It uses the signal "javaScriptAlertSent" to do the trick (is there another way to be notified of the "onLoad" event from outside the page context?) * It uses a "private" slot "_appendScriptElement" to pass the script url in the page context (is there a better way?)
