Code blocks use short pygments class names, but inline code uses long ones

Describe the bug

This error was originally reported on https://stackoverflow.com/questions/21591107/sphinx-inline-code-highlight

code-block directives use short pygments class names. Inline code snippets (the code role), on the other hand, use long Pygments class names. As a result, inline code snippets are not properly highlighted.

To Reproduce

$ mkdir /tmp/sphinx
$ cd /tmp/sphinx
$ sphinx-quickstart
…
$ # edit index.rst as shown below
$ tail index.rst
* :ref:`search`

.. role:: bash(code)
   :language: bash

Test inline: :bash:`export FOO="bar"`.

.. code-block:: bash

    export FOO="bar"
$ make html
Makefile:20: warning: undefined variable 'O'
…
The HTML pages are in _build/html.
$ firefox _build/html/index.html 

Expected behavior
Both code snippets should be highlighted. Insetad, only the code block is highlighted. The inlien snippet has pygments classes applied, but they use long class names, and so they don't match the syntax-highlighting CSS rules, which use short class names.

Environment info

• OS: GNU/Linux (Linux Mint 20)
• Python version: Python 3.8.2

Thank you for reporting. But that was already reported at #5157. So I'm closing this as dup.
