With the work on bug 1770731 support for platform objects of type `Node` gets added. The one thing which is missing is all around Shadow DOM support. The following should cover it: * `shadowRoot` field of a DOM element * serialization of a ShadowRoot node * serialization of elements from within a Shadow DOM Maybe we should do this work with an alignment of Shadow Root related support for Marionette.
