This is a regression from bug 1450250, which removed a if (!GetCx()) early return in this function. That early return was wrong, both because it prevented elements that were in shadow trees from targeting other elements, but also because that check was not present in AfterSetAttr, which means that dynamic updates to the attribute would work. Pass the SVGAnimationElement itself to resolve references. That's what we do for attribute mutations, and also it's the same behavior we have, since the ID lookup IDTracker does only depends on containing shadow root and containing document, and that's invariant between a kid and it's DOM parent. Some other code has been updated to take references instead of pointers so the null-safety of those methods is explicit.
