That Pandoc output looks correct to me.  Is there a gotcha I do not see?
If not, then that is exactly what I would expect from the Org parser.

Yes, that much is given.  Without an extensive test suite, working on a
parser would be nothing but a waste of time, and the end result would
be, at least for us humans, an infinite stream of bugs.

Honestly?  That sounds like a wrong approach to parsing.  (And if that
is the case, then that could explain why I keep fighting the Org parser
on a daily basis, compared to practically never in every other language
I use.)
