Comment (by stevenkword):
On second thought, that would only prevent the problem if you hit a
`/feed/` or `?feed` URL. If you actually hit any other page belonging to
the same site as the widget, the problem would still occur. Short-
circuiting `is_404()` wouldn't prevent the problem either if say the URL
of `example.com/hello-world` was entered as the feed source. You will get
the notice in the widget that notifies you the feed is invalid, but if it
were currently valid and then not valid in the future, the problem would
persist.
