Unselectable prompt in code-block

[Ron Stone]

Hi,

I am using Sphinx 4.2. I see this merge re making prompts in code blocks unelectable. 

https://github.com/sphinx-doc/sphinx/pull/9120

I don't see any documentation of how this works here:

https://www.sphinx-doc.org/en/master/usage/restructuredtext/directives.html?highlight=code-block

and building a typical code-block such as the following does not demonstrate changed behaviour. 

.. code-block:: bash

    

   ls

or 

.. code-block:: bash

    

   $ ls

Can someone please explain how this is configured and invoked?

Thanks.
