Incorrect colour shown for the second double-backticked literal in a comma-separated list of pairs in a specific form

[jonathandung]

Type: Bug

I am making a table of the audit events raised by my python library mimicking this page. Within a list-table entry (not sure if that's relevant), when I type in the arguments of the audit events and their corresponding python types in the following format:

.. list-table: foobar
  :header-rows: 1

  * - A
    - B
    - C
  * - spam
    - ``arg1``: :class:`int`, ``arg2``: :class:`str`, ``arg3``: :class:`bytes`, ``arg4``:  :class:`float`
    - ham

The second argument and the type of the first argument show in the wrong colour. I expected `int` to be blue, the colour of other directive contents; the comma to be white (I'm in dark mode), and ``arg2`` to be orange, the same colour as other double-backticked literals. However, they all displayed in pink, which is the colour of directive roles.

This issue is especially strange since the other parts of the text were highlighted correctly.
