CSS style unreadable for Mermaid dark mode
Looks fine in light mode, text unreadable in dark mode.

Thanks for firing up this issue. After some investigations, I found that it consists of 2 issues:
- The mermaid stylesheet is outdated. Mermaid now embed styles inline when generating svg. This stylesheet should be removed (from our webpack config).
- Night mode implementation for mermaid is also outdated. Latest mermaid provides 4 different themes. We should feed in mermaid theme option based on current theme, and then trigger a rerender. https://github.com/hackmdio/codimd/blob/558fa5fcf46b0a94c49c503c2e1373c86829ff1e/public/js/extra.js#L397
