The Emacs Info reader and the stand-alone Info reader are two
different implementations of the same informal specification.  There's
no formal specification of the structure of a valid Info file.  So
there's little hope for both of them working identically in bordeline
cases such as this one, especially since they are written in two very
different programming languages.  As a matter of fact, they have
different features, albeit minor ones.

I would also argue that an entry in DIR without a newline is a bug in
whatever procedure you followed to install that Info manual.

Bottom line, my recommendation is not to try to fix this, at least not
now, for fear of breaking something more important at the time when
the efforts are on fixing real bugs (of which there are too many, IMO)
in order to begin the pretest.  But that's me.
