-interface ElementList extends List<Element> {

Not sure I follow.

ElementList extends raw List so that classes implementing ElementList may be
cast to List<? extends Element>.


So why not declare 
interface ElementList extends List<? extends Element> ... 
?

+// may be cast to List<? extends Element> - e.g., List<CanvasElement>.
+interface ElementList extends List {
   // TODO(jacobr): add element batch manipulation methods.
   ElementList filter(bool f(Element element));
 
   ElementList getRange(int start, int length);
 
   Element get first();
   // TODO(jacobr): add insertAt
 }
