Comment on file gets removed while writing

Summary

While writing a comment on a file, if you scroll far out of view, all the text you have written gets removed.

Steps to reproduce

Open a large merge request, start writing a comment on a file, and scroll far out of view. When scrolling back, the content you had started writing is removed.

This is quite annoying, as sometimes, when reviewing a larger MR, you want to go back and forth reviewing things while you write your comment. The current bug means you basically have to write your entire comment in one go, or write it outside of gitlab and copy paste in your comment afterwards. In any case, it becomes very inefficient, and frustrating when you forget about it and it happens.

This has consistent behaviour on macOS Sonoma Version 14.4, Chrome Version 127.0.6533.74, on Gitlab.com.
