Consider a clip-path url() reference an empty clip while it's loading
While an external clip path is loading, we'll currently render as if no
clip path is applied. Not applying a clip is what the spec prescribes
for invalid references. While the resource is loading though, we
shouldn't consider it invalid. Instead let an empty Path represent the
external reference while it is loading.
