rendering strikethrough

Describe the bug markdown strikethrough is not rendered under my jupyter book environment, while it shows nicely in classic notebook

my notebook renders a markdown table like this

resulting html book renders this instead

To Reproduce

any text marked as strikethrough using markdown ~~ - not necessarily in a table btw - will exhibit the issue

Expected behavior

Would expect the default behaviour of jupyter book to be in line with the default behaviour of jupyter (classic in my case); I am not aware of any customization I would have done on the classic end - although my memory may be failing me here)

if this is a configuration option, it’d be nice if it showed up when searching for strike in the readthedocs documentation

Environment (please complete the following information):

$ python --version
Python 3.7.4
$ jupyter book --version
Jupyter Book: 0.7.0
MyST-NB: 0.8.3
Sphinx Book Theme: 0.0.27
MyST-Parser: 0.9.0
Jupyter-Cache: 0.2.2

Additional context Add any other context about the problem here.

@parmentelat nope, you are correct! We are in the process of updating the various parts of the MyST stack to their latest versions in Jupyter Book - check that effort here:

Note this will be partially supported (HTML only) in a future jupyter-book release, once myst-parser v0.17 has been released and “bubbled up”: https://myst-parser.readthedocs.io/en/latest/syntax/optional.html#strikethrough
