Description

First of all, I love macdown very much and I use it everyday. Thanks for such a great tool!

When I sometime use the latex function, I noticed that by enabling the latex render in the setting, it makes macdown slow while typing and scrolling. This happens even though there are no latex currently on the visible area of the document. (I have a document about 10 A4 pages long, and it contains about 5 latex equations.) I guess this is because it constantly connect the internet for rendering the equation. Therefore I am wondering is that possible to make Latex available without internet? Maybe be downloading all the MathJax(?) to a local storage?

Research direction
This issue requests offline LaTeX rendering by bundling MathJax locally. Investigate the current LaTeX rendering implementation in MacDown, which likely uses a WebView with MathJax loaded from a CDN. Review the comments on the issue for suggested approaches and any pointers to relevant source files. The main challenge is obtaining a local copy of MathJax and configuring the web view to use it without network requests. Look into the app's resource bundling mechanism to include MathJax files.
