+/**
+ * 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.
