Ohh - it might be worth adding a TODO for this. In the future we could add an
@HtmlImport here to load that file and that way we guarnatee it is loaded (in a
way similar to how we include it automatically in the code generated for the
code/paper elements)

Good point, I like the idea of just moving it to an @HtmlImport. We will need to
make sure everything uses that instead of linking the js file directly though.

Added a todo for it.

+class CustomElementProxy implements Initializer<Type> {
+  final String tagName;
+  final String extendsTag;
+
+  const CustomElementProxy(this.tagName, {this.extendsTag});
+
+  void initialize(Type t) {
+    registerDartType(tagName, t, extendsTag: extendsTag);
+  }
