Today I ended up on possibly a related issue with ob-shell results.

Observations:
1. Issue triggered when using :session
2. Output text is OK for the the first shell src block's output. But for
the second block, the output before '>' gets truncated.

Here's a minimal reproducible example:

=====
#+property: header-args:shell :exports both :results output :session
*ob-shell-session-issue*

#+begin_src shell
echo "1 > 0"
#+end_src

#+RESULTS:
:
: 1 > 0

#+begin_src shell
echo "1 > 0"
#+end_src

#+RESULTS:
:
: 0
=====

The root cause seems to be similar, with detection of shell prompt: '>',
'%', etc. when session is enabled.
