Just a list of internal issues, I have wrestled with. For future reference.

Syntax Highlighting & Mathjax % uiOutput

If you don't call withMathJax in the main app UI, late uiOutputs cannot be set. No content will be shown.
In an earlier version, withMathJax destroyed uiOutputs when no code is rendered... we don't know yet the current, state.
Need extra call to highlight.code.script() script in outputs that are dynamically shown created needed.
We add highlight.code.script() in the ui list of a block that will be dynamically rendered and can contain code HTML. Examples are frame, and task_block.
The function highlight.code.script() interferes with withMathjax. highlight.code.script() must be called inside withMathjax.
The commonmark package does not render with MathJax
If there is no internet connection, we must not call withMathJax, chunks won't be shown otherwise.
