Listing caption is missing a space

[PierreMarchand20]

When using numfig = True in config.py and a code-block like

.. code-block:: cpp
    :caption: main.cpp
    :name: main_multiple_file

    #include <iostream>
    int main(){
        std::cout << "Hello world!\n";
        return 0;
    }

there is no space between Listing x.y.z and the caption:

I came across this same issue. This is a reproducer using a fork of this repo:

• But code blocks are missing a space:
