For a `revealjs` document format, Mathjax is configured as follows
```
      math: {
          mathjax: 'https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.0/MathJax.js',
...........
          },
        },
```
while for a `book`, we get a more recent version of MathJax
```
<script src="[https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-chtml-full.js](view-source:https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-chtml-full.js)" type="text/javascript"></script>
```

Is it intentional, or should it be considered a bug?
Can I specify the version of MathJax I want to use?
