Hello Nicolas,
Thanks you so much for trying to reproduce my observation.
I see the discrepancy that you have uncovered...
It seems that to reproduce the problem, the drawer must be
inside the body of a headlined section.

So, simply adding a headline above the drawer should allow
you to reproduce the problem.  For example:

* Testing drawer that closes unexpectedly

:mydrawer:
  - Plain list item with children
      + some notes here
      + and here
      + some more here
:end:

Looking forward to hearing again from you.

Kind Regards,
/Mitch
