------------------------------------------+--------------------------------
 While working on #26962, Kathy and I discovered that first party isolation
 breaks the behavior of the default uitour permissions (listed in
 `browser/app/permissions`). This bug makes it impossible to use a default
 permission for an https:// site. We have a patch which we will post soon.
