In order to tailor certain security checks to the caller that is attempting to load a particular piece of content, we need to be able to attach an appropriate triggering principal to the corresponding requests. Since most HTML content is loaded based on attribute values, this means capturing the subject principal of the caller who sets those attributes, which in turn means we need to make it available to `AfterSetAttr` hooks on all relevant element types.
