描述

The following document contains some math which is nicely displayed in the editor but when downloading as html the math becomes ugly and some things completely fail.

This is a regression that occurred both on hackmd.io and in codimd. Back in March when I wrote that document on hackmd.io the downloaded html displayed fine. Yet the exact same html that I downloaded in March doesn't render properly anymore now.

Edit: When I copy the head from the HTML of the online editor the math displays correctly again. So I guess it would be just a matter of updating the head used for the "Download HTML" function.

@jackycute You are working on hackmd.io, right? Maybe you could fix it there too? :P Btw, do you have a separate bug tracker for hackmd.io ?

Edit 2: https://github.com/hackmdio/codimd/issues/885 (inlining the resources) might have prevented the regression.

研究方向
The issue describes a regression where math rendering fails in downloaded HTML. The user suspects the head of the HTML export is outdated. Investigate the export HTML function (likely in the lib/ or controllers/ directory) and compare the included script tags for math rendering (MathJax or KaTeX) with the current online editor's head. Also check the linked issue #885 about inlining resources which may have caused the regression. Update the download HTML head to match the editor's head, ensuring correct math display.
