Adds a new keyword named "allow-top-navigation-by-user-activation" for iframe sandbox, which requires a user activation (or gesture) being processed to trigger a top-level navigation. This change would enable more use cases of sandboxing untrusted third-party contents (eg., ads) by allowing top navigation while blocking malicious auto-redirecting, and thus help building a safer internet (eg., a safer ads ecosystem in which all ads could be sandboxed to prevent malicious auto-redirecting).
