Callbacks from extended Custom Element are not triggered

(defwebcomponent test-shadow-dom-1
  :document "<div></div>"
  :on-created #(.log js/console "created 1"))
(defwebcomponent test-shadow-dom-2
  :host :test-shadow-dom-1
  :document "<span></span>"
  :on-created #(.log js/console "created 2"))

When creating a test-shadow-dom-2, test-shadow-dom-1 on-created handler is not called and a single ShadowRoot created.
