+At the time of inserting the meta
element to the document, it is
+possible that some resources have already been fetched. For example, images might be stored in
+the list of available images prior to dynamically inserting a meta
+element with an http-equiv
attribute in the Content security policy state.
+Resources that have already been fetched are not guaranteed to be blocked by a Content
+Security Policy that's enforced late.
