That error "maximum nesting of 10 spans reached!!!" is a safeguard against an infinite loop. In version 2.0, due to changes in the parser logic, is no longer needed, so it's fixed.

Hi, when is 2.0 expected to ship?

For a quick fix I added this npm script to my package.json, "postinstall": "sed -i '' 's/=== 10/=== 1e4/' node_modules/showdown/dist/showdown.js",

1.9.1, January 2nd 2022, still. Any known fixes?

turns into the following html

The issue seems to really come from using markdown within regular html nodes.
