[BUG] LaTeX Suite will significantly affect Obsidian’s performance.

Description

I once posted this https://forum.obsidian.md/t/i-have-tested-the-13900k-3090-7950x-4090-and-7950x3d-4090-and-there-is-a-serious-issue-with-canvas-performance-no-configuration-can-smoothly-run-a-canvas-card-with-26-000-characters-of-content/81855/19
on the Obsidian forum. After testing, I found that the input lag in canvas and markdown caused by plugins is mainly due to LaTeX Suite.

Generally, when the input in canvas cards and markdown exceeds 10,000～25,000 characters (markdown documents can be higher), enabling the LaTeX Suite plugin will cause lag in English, Chinese Pinyin, and LaTeX input. Note that this input lag also occurs with regular Chinese and English input. Because the $ ... $ mode cannot use the tab key to automatically input &, I mainly use version 1.7.4

I tested the latest version 1.9.4 and the situation is the same. Even without inputting LaTeX, enabling the plugin causes lag when typing in both English and Chinese. The lag is more noticeable in canvas cards than in markdown files. Generally, canvas cards start to lag at around 10,000 to 20,000 characters, while markdown files may start to lag at around 40,000 characters. Disabling the LaTeX suite and restarting the program significantly alleviates the issue.

This is still happening and really bad. Typing in any kind of LaTeX block start to lag and I need to wait at least half a second for the character to appear or for the cursor to move. Typing outside the LaTeX block works fine but inside it lags bad.
I disabled Latex and the lag stopped. The note I typed in had only around 1,4k characters and most of them in LaTeX blocks. Although I have experience this lag in smaller documents too. My current LaTeX suit version is 1.9.8.
I love this plugin and would love to get a performance updates since it makes math almost unbearable to type.

TLDR. Lags badly in LeTeX blocks. Pls fix.

Ok, so I fixed the lags I noticed myself and also I have to say it was not as bad as I thought. The main issue came from the Copilot plugin I had installed. Still not good but not as bad as I thought.
