* Bug 1624853 - Shim Storage Access API on history.com
*
* history.com uses Adobe as a necessary third party to authenticating
* with a TV provider. In order to accomodate this, we grant storage access
* to the Adobe domain via the Storage Access API when the login or logout
* buttons are clicked, then forward the click to continue as normal.
