autocomplete gives duplicated text in nix

[aster-void]

Summary

When I autocomplete this,

pkgs.tailwindcss-<cursor>

I sometimes get this

pkgs.tailwindcss-tailwindcss-language-server<cursor>

which is not what I expect.

apparently it sometimes happen when I autocomplete package that consists of more than or eq to two words, separated by -
I'm not sure if this is helix or nixd bug.

Reproduction Steps

I tried this:

1. install nixd, which gives the autocomplete feature
2. hx example.nix
3. write below in example.nix

{pkgs}:
pkgs.tailwindcss-language-servre

4. delete the last 2 words

{pkgs}:
pkgs.tailwindcss-

5. append lang so it becomes

{pkgs}:
pkgs.tailwindcss-lang

6. wait for the autocomplete and press tab

I expected this to happen:

it completes to tailwindcss-language-server

Instead, this happened:

it gave me tailwindcss-tailwindcss-language-server

it's inconsistent so you may have to try a few times to get it to reproduce.
