2.5-3build2 from Ubuntu-20.04 works in the same way.

I like such behavior:

echo "/lorem =ip/ sum= dolor/" | pandoc -f org -t latex
\emph{lorem \texttt{ip/\ sum} dolor}

I know at least one more persons who will be happy as well:

mid:87pmtqp79s.fsf@web.de
(tracked as a confirmed bug at https://updates.orgmode.org/)

printf '/lorem\nipsum [[https://orgmode.org/,service][dolor]] ipsum/\n' 
| pandoc -f org -t latex
\emph{lorem ipsum \href{https://orgmode.org/,service}{dolor} ipsum}

Nicolas Goaziou explicitly stated that current behavior is correct, see 
"[Patch] to correctly sort the items with emphasis marks in a list".

Nicolas confirmed it when I posted a similar example later in the 
following discussion:

And once more in response to my message:

So formally this feature of pandoc is a bug (due to different kind of 
parser). It is the reason why a corpus of tests should exist in a format 
that can be easily imported from various programming languages.
