Some documentated MyST options are ignored

[alcrene]

As far as I can tell, a number of documented options MyST parser are actually ignored by Jupyter Book's config file parser. I noticed this for the following two:

• myst_linkify_fuzzy_links
• myst_dmath_double_inline

but I suspect the problem is more generalized. The last one is even set to True in the default config file, but when checking the compilation output, one sees that all builds actually use False.

The problem seems to be that those options are never read by config.py: https://github.com/executablebooks/jupyter-book/blob/1ee1a88468ef3616c24e64577c2ce332000807f7/jupyter_book/config.py#L339-L342 When I add "myst_dmath_double_inline" to the list on line 340, then inlined display equations are recognized as expected.

@alcrene Did you identify a workaround? Same issue here

[alcrene]

@adelavega I don't know of a simpler workaround than forking the repo and making the tiny one line change I outlined above. If you don't need to worry about users, I would consider that a viable temporary solution.

thanks for reporting this @alcrene. Sorry for the delays in getting back to this. It sounds like after https://github.com/executablebooks/jupyter-book/pull/1842 is released we need to harmonise some of the myst options that are available in the top level Jupyter-book cli.

I also ran into this. The proposed solution works for me.
