I do not know by which settings, but I do see that Org snippets with
programming language inside behave just as the mode:

If I have this in Org:

#+begin_src emacs-lisp :results output silent

Then I can see syntax highlighting and I get indentation as well. But
not all features.

Maybe soolution could be to narrow-to-region, change the mode, and
then by exiting from narrow to region to change it back to original
mode. It could be one function.
