Summary

This issues is for tracing marked and related dependencies upgrade.
As per to current incompatible and related dependencies outdated, the marked js upgrade stuff is tough to move on.
For avoiding the vulnerabilities issues, we should upgrade mark js asap.

Update

Kudos to @dzsibi help the upgrade and @paulhibbitts verified this changes.

We update marked.js to 4.2.12 and make some changes to fix the upgrade issue in #1993 .

In case of the unpredicted issue for this change, the parser breaking especially.
Hold this issue thread to trace and collect report of the marked issue.

Breaking

Maybe not support the IE11 from the next release since marked.js removed the support of IE11. 💣

Will the code help you?

<script src="https://cdn.jsdelivr.net/npm/marked@4"></script>
<script>
let newMarked = marked; // I find that marked will be overwritten by Docsify, so save it before
window.$docsify={
  markdown: (originMarked, originRenderer) => newMarked.parse // markdown: newMarked.parse
};
</script>

I saw it from upupming/docsify-katex#36. I think replacing 'marked' with 'marked.parse' will help the latest marked work well in Docsify.

// Docsify library source code
import {marked.parse as marked} from marked // the newest version

I can prove Docsify will use the latest marked to parse markdown because the built-in marked doesn't support the extension, but the newer one does, which helps me to parse math formula
