It looks like we always allocate an AuthorStyles in the ShadowRoot constructor. In the case of <svg:use>, we don't do anything with stylesheets in the shadow tree, so the AuthorStyles there is unused. In fact, maybe we should consider allocating AuthorStyles lazily in general, for all the cases when shadow trees don't have styles inside them.
So that we don't waste a bunch of memory with stuff like <svg:use>. I plan to shrink AuthorStyles further, but this should help regardless, and isn't very complex.
