/**
 * Bug 1790750 - The page is blank on relearnings.com/linkedinlearning.html
 * with ETP set to Standard
 *
 * The linkedin video iframe loaded on relearnings.com/linkedinlearning.html is
 * denied storage access by ETP due to being a tracker breaking the website.
 * Since the iframe is a video which users want to access if visiting the URL
 * this intervention sets the window location to the iframe URL allowing it
 * first party storage access.
