描述

MathJax appears to account for about 1/3rd of our (2.9MB large!) editor bundle, and codemirror appears to be the second-largest contributor. If we were able to lazy-load these as required, we may be able to improve editor startup time for users who don't use MathJax or the HTML editor by default. We're also using the full MathJax bundle - maybe there's a way to lazy-load the required parts? A good starting point would be to just strip them out and compare editor loading time before and after, to see what sort of performance gains there are.

研究方向
Start by examining the editor's webpack configuration to locate where MathJax and CodeMirror are bundled. Then implement dynamic imports for these libraries and compare bundle size and startup time using browser DevTools or webpack bundle analyzer. Document the performance improvements before submitting a PR.
