== commands.follow ==
On XUL pages/windows, <body> does not exist (hence the check was put
in), but is `null`, so can be safely compared against (and the check can
be omitted).
== helper_follow ==
Since the last war on isXULDocument, the namespace has in many cases
been moved from the document root to a descendant (e.g. to <body> on
about:preferences in fx73). This means that the isXULDocument call often
isn't triggered when it should.
Coincidentally, most XULElements are recognized, either due to them
being implemented as a custom element containing a recognized element or
by their tag name being identical to a recognized one. The only
exception is <xul:label is="text-link">, which needed special handling
in commands.follow_in_tab().
