A modern programming language that makes developers happier.

Anyone have problems with IntelliJ is extremely slow when editing markdown. Simple text mode, no preview. Started in the release before the last one.

I've noticed this specifically working with markdown tables.

<@U0195MWDYES>, can you please clarify step-by-step scenario of the issue reproduction? Thank you!

<@U04JDQ5TV6E> Sure, I do nothing special. I use the `README.md` linked below. I open, try to edit and its remarkably slow. I suspect the tables. When they come visible the scroll starts to lag very badly.

Also, I had to switch off the language detection completely because it started to require the imports. Then it haven't been able to resolve the dependencies of those imports. As a result half of my markdown file was red.

To reproduce:

1. IntelliJ - New Project - Empty Project
2. Copy the linked README.md
3. Open it, try scroll

Ah, IntelliJ Info:

IntelliJ IDEA 2023.2.1 (Ultimate Edition)
Build #IU-232.9559.62, built on August 23, 2023

I started to notice the problem one version before the above.
