Currently we have a delegate plugin under formBehavior that is specific to forms. We should instead expose something more general, that allows proxying any set of properties.
It should support specifying either specific properties to proxy, or entire objects (e.g. the forms use case is "all ElementInternals properties that are also present on form elements and are not defined by HTMLElement or a parent class").
