Add a containing div element to the "still waiting" component chunks

And drop the use of a list.

The list was annoying because it was triggering the React warning:

	Each child in a list should have a unique "key" prop

And in this case, it seemed really silly to have to name/distinguish
the <p> element from the following <ul> element.

And this new <div> does give us a logical place to treat this chunk of
the document as a single element if needed, so this is the logically
correct thing to do.
