Bug 1928932 - Part 1 - Add an mIsTrusted flag on script elements. r=smaug,credential-management-reviewers,dimi
This flag can be modified when notifying for character data change, content appending, content insertion and content removal by specifying a MutationEffectOnScript flag. By default callers other than the HTML5 parsers always specify "drop trustworthiness" but mIsTrusted flag is not used anyway, so there is no behavior change. Spec: https://w3c.github.io/trusted-types/dist/spec/#enforcement-in-scripts PR: w3c/trusted-types#579 Differential Revision: https://phabricator.services.mozilla.com/D252020 UltraBlame original commit: bb51e4ab08008c6f6920e651994b59de56d19383
