Sorry if I'm wrong.

I think the algorithm of olderShadowRoot of HTMLShadowElement should consider
activeness.

Let's consider the case a non-active shadow element is the first shadow
instance, and active shadow element is the second shadow instance. The first
shadow instance should return NULL and The second shadow instance should return
the assigned ShadowRoot instead of NULL.
