* Bug 1802340 - tsn.ca login broken with dFPI enabled
*
* tsn.ca relies upon a login page that is out-of-origin. That login page
* sets a cookie for https://www.tsn.ca, which is then used as an proof of
* authentication on redirect back to the main site. This shim adds a request
* for storage access for https://www.tsn.ca when the user tries to log in.
