bug: `pylsp` deletes all python code on save

[cgahr]

Summary

I have format on save enabled. When I save my file, pylsp deletes my whole python document. pylsp is installed from nix. This issue didn't exist with helix 23.05.

Reproduction Steps

1. start hx
2. open python file
3. :w
4. lose everything in the current file

language.toml:

[[language]]
auto-format = true
name = "python"

[language.indent]
tab-width = 4
unit = " "

[language-server.pylsp]
command = "pylsp"

[language-server.pylsp.config.plugins]
[language-server.pylsp.config.plugins.black]
enabled = true

[language-server.pylsp.config.plugins.mypy]
enable = true

[language-server.pylsp.config.plugins.ruff]
enable = true
