You can show multiple widgets in one buffer today, which wasn't the
situation a couple of years back.

It should work, but take care that the _same_ xwidget is never displayed
on-screen in more than one place at any given time.  If it is, then one
of the xwidget views will not display.

This is a known problem that I'm trying to resolve, it will probably be
a temporary limitation.  Thanks.
