> Upgrading insecure requests MUST not interfere with an authors' ability to track down requests that would be insecure in a user agent that does not support upgrades.

> When sending a violation report for an upgraded resource, user agents MUST target the Document or Worker that triggered the request, rather than the Document or Worker on which the upgrade-insecure-requests directive was set. Due to §3.3 Policy Inheritance, the latter might be a cross-origin ancestor of the former, and sending violation reports to that set of reporting endpoints could leak data in unexpected ways.
> Likewise, the SecurityPolicyViolationEvent MUST NOT target any Document other than the one which triggered the request, for the same reasons.
