Elements Shouldn't show Polymer's internal API

[manolo]

Description

Elements directly extending the Polymer.Element, shouldn't show methods listed in Polymer.ElementMixin or Polymer.PropertyEffects

Expected outcome

Create a new element with polymer init and add iron-component-page to its index.html.
Since the element does not have any method, the API should look:

Actual outcome

The API of Polymer.Element is listed instead

Note that just when the simple element extends an empty mixin, the problem is fixed.

  /**
   * @polymerMixin
   */
  Foo = superClass => class FooMixin extends superClass {
  };

class KkElement extends Foo(Polymer.Element) {
...

Probably the issue might be fixed in the analyzer.

Something I would really like to see which would fix this nicely is to add checkbox's to enable/disable each source of inherited properties/methods so you can focus on just what you care about.

Friendly ping to @aomarks. 🙂

@manolo Another one liner workaround is:
class SomeElement extends (class extends Polymer.Element {})
