[w3c/webcomponents] Composite custom element is not defined until the parent element is connected (#765)

I have a host custom element that receives as dependency another custom element. And still in the host constructor, I need to access some parameterized data from this dependency. However, because the host is not yet connected, the element inserted in the slot has not yet been defined.

I do not know if this is a design decision, but it is particularly annoying. Even more so because there are workarounds not very elegant, such as cloning the dependency, which will return a registered node, and replace the original node by the clone.
