This change captures the subject principal when a scripted caller sets the textContent or innerHTML property of a <style> node, and uses it as the triggering principal for the resulting stylesheet. If the node contents are modified in any way other than through textContent or innerHTML, the triggering principal is forgotten (which is an intentional design feature).
