When cloned, a custom element looses it's constructor class and it's custom methods

[Laurent-Chouinard]

Bug report

Fiddle

https://jsfiddle.net/say37z8m/2/

Explanation

• What is the behaviour you expect?
  I expect the clone method applied on a CustomElement to produce a CustomElement with the same constructor and same available custom methods (on the prototype) as the source element.

Should I write a custom clone method then? I don't know how to write one that works. my custom cloning introduces a problem with the tree model in the parent/children relationship

• What is happening instead?
  the clone method returns an instance of the mother class and I loose access to my custom methods. The clone is not an instance of CustomElement anymore

• What error message are you getting?
  When calling a custom method I get the behavior of the mother method of the same name or a TypeError "not a function" if the mother class doesn't have a method of that name.

Thank you so much for this great library.
