mdx_bleach is broken

[pbelmans]

The Gerby-flavored / Stacks-flavored Markdown is broken with an up-to-date Python installation, because mdx_bleach is out-of-date. This must be fixed.

The "solution" for now is

pip3 install 'markdown==2.6.9' --force-reinstall

In case anyone else wants to try the workaround by downgrading: since python-markdown-math==0.7 requires Markdown>=3.0 I also needed to downgrade python-markdown-math to 0.6.

Running into the same issue. Instead of downgrading I used a patched version of mdx_bleach. I made a fork were I describe the patching, here:
