Describe the bug

Example:

The equation goes as

\text{Attention}(Q, K, V) = \text{softmax}\left(\frac{QK^\top}{\sqrt{d}}\right)V

and is logged correctly in rss feed file.

However, the same equation is rendered in Follw as below:

FOL-1703 Renderer cannot process latex fraction

[PrinOrange]

You should process them with KaTeX or MathJaX and transform the TeX code into HTML structure manually in your pre-procession.

Since Follow already added support for latex in https://github.com/RSSNext/Follow/commit/ef8939868986cbbdc3f00cc865b3b435a611b936 , I think it might be better to implement fraction support on Follow's side rather than RSS generators', as you cannot force all site owners to transform TeX code manually into HTML.

I think the RSS specification requires the content to be HTML
