Complete using LSP texlab for Latex is broken

[pozix604]

Summary

Completion is incorrect, but texlab itself works in other editors, e.g. vim + ale.

Expected behavior is as shown in the video at https://github.com/latex-lsp/texlab.

Same error with texlab versions from crates.io 4.3.2 and github 5.12.0.

Reproduction Steps

1. hx --health latex --> OK
2. hx test.tex
3. Type \documen

Not sure if this issue is still being worked on, but I could not gather logs on my Debian 12 WSL. However, the issue is also reproducible on Windows 11. I'm new to this project, so I am not sure if the logs will be the same on Debian 12. If they are different, can you submit them? Here are the logs on Windows 11:

I can reproduce this.
However, when I open an existing LaTeX file that already has a preamble + some content,
completion with texlab works as expected.
So it doesn't seem fundamentally broken.
