Anyone knows a #markdown editor for #macos that supports attributes?

I’m using this Markdown-it extension to add classes to images in my #eleventy projects, for example: https://www.npmjs.com/package/markdown-it-attrs

Not yet supported in:
- #MacDown: https://github.com/MacDownApp/macdown/issues/1112
- Visual Studio #Code ’s MD Preview Enhanced: https://github.com/shd101wyy/markdown-preview-enhanced/issues/1258
