Used section-level is to high

[danwos]

If I have the following code:

chapter 1
=========

chapter 1.1
------------

chapter 1.1.1
~~~~~~~~~~~~~

.. test-env:: xy.json
   :env: env_1, env_2

Then the sections structure looks likes this.

• chapter 1
  • chapter 1.1
    • chapter 1.1.1
    • env_1
    • env_2

That's not so nice, as for normal cases the author wants the env-information be part of the last defined section. So it should look like this:

• chapter 1
  • chapter 1.1
    • chapter 1.1.1
      • env_1
      • env_2
