tailwind LS gives invalid suggestions when started after first -

Summary

tailwind LS gives invalid suggestions when the completion starts after first -

Reproduction Steps

https://asciinema.org/a/8CCtaplo2JFn3z2ZfoJeZgluL

I have created a repro repo s.t. you don't have to.
https://github.com/aster-void/helix-repro/

I tried this:

1. install tailwindcss-language-server
2. initialize a tailwind project (i.e. create tailwind.config.js with some text)
3. write something like this, then wait for the LS to start completion:

<div class="text-[cursor]"></div>

3.1. if the completeion starts too early, write text-red then delete the red part
4. continue writing red

I expected this to happen:

it should suggest text-red-[number]

Instead, this happened:

it suggested divide-red-[number], which doesn't match what I have

It could be related to #12501. @nik-rev What do you think?

what #12501 does is check if the documentation for each Color item ends with a valid hex code, and if so, use it to display a colored box. It doesn't affect the completion algorithm at all

Two years ago helix and neovim had some issues with tailwindcss lsp, I forked their lsp and fixed that issue, as well as sorting after you type -. It's up with master, new branch. Of course, it's just temporary solution.

are you planning on submitting your changes upstream?

No, because I don't think that this time it's bug on tailwindcss lsp. Same completion items are returned when I use vscode(about 12k items), and vscode shows only important ones microsoft/vscode#79516.
This is how helix sorts completions.
