Bug: using :wrap src interferes with :cache yes with :var [9.3 (release_9.3 @ /usr/share/emacs/27.1/lisp/org/)]

I think there is a bug with the `:cache' header and how results of
evaluation are wrapped: Using `:cache yes' and wrapping the results
prevents later blocks using the cached results.

To reproduce, start with an example like the one at the bottom of the
documentation in
<https://orgmode.org/manual/Evaluating-Code-Blocks.html>. Then add
something like `:wrap src R' (or `:results value drawer') to the header
of the block named `random' and the second block produces `nil' instead
of the desired result.

I verified the bug using `emacs -nw -q' with version 9.3 but would be
happy to send more information if the above is not enough to reproduce.

Thanks.

I tried to evaluate the following in various orders.

#+NAME: random
#+BEGIN_SRC R :cache yes :wrap src R
  runif(+1)
#+END_SRC

#+NAME: caller
#+BEGIN_SRC emacs-lisp :var x=random :cache yes
  x
#+END_SRC

I am unable to see any issues with the latest development version of Org.
You may try to update Org and check on your side.

Canceled, for now.
