Re: [webcomponents] Custom elements disconnected from a document should not be upgraded (#419)

Since the registry is per realm now, it's relevant whether the following two questions are asked for when done in `window.document` and/or elsewhere.  It would be weird for elements created inside a DOM API not to get the flag set just because it internally uses fragment parsing or cloning.  I think whatever behavior we define must be same for both; i.e. either yes for both or no for both.
