Automatic update from web-platform-tests [@scope] Expand :scope selectors for :has() cache The :scope pseudo-class can refer to different elements depending on context. This is similar to the '&' pseudo-class, but differs in that :scope refers to a single *element*, not a specific selector list. This causes problems for the :has() cache, since it uses the serialization of a selector as the key. In CL:5680906, this was solved by expanding '&' in the cache-key, and this CL now does a similar trick for :scope. Unlike '&', however, the :scope selector itself does not know what it refers to; it must come from context. We can use the pointer value of the scope node for this, since the :has() cache only exists on the stack during style recalc.
