The integration with Elm LS doesn't work when Zed opened in idiomatic way

[Janiczek]

This might be a more over-arching Zed issue rather than one specific to this extension.

Steps to reproduce:

1. Open Zed on macOS via Spotlight or opening the Zed.app application via doubleclick.
2. File -> Open (Cmd+O)
3. Locate the project root, open it
4. Try to save an Elm file

✅ Expected: A file gets reformatted.
❌ Actual: File stays as-is, an error gets shown in the status bar + logs:

2025-05-19T09:32:26+02:00 INFO  [project.lsp_format] Formatting via LSP
2025-05-19T09:32:26+02:00 ERROR [project::lsp_store] Formatting failed: failed to format via language server: Request textDocument/formatting failed with message: No Elm workspace contains /Users/martin/Localhost/cara/compiler/src/AST/Frontend.elm
2025-05-19T09:32:26+02:00 ERROR [editor] failed to format via language server

Caused by:
    Request textDocument/formatting failed with message: No Elm workspace contains /Users/martin/Localhost/cara/compiler/src/AST/Frontend.elm

Workaround / what's wrong

When I instead open Zed by opening my terminal in the project root and running zed ., everything works correctly (formatting, diagnostics, etc.)

It's surprising (a bug?) that the "open" action from an already opened Zed application isn't the same thing as doing zed ., with regards to (I presume) the current working directory.

Are you still seeing this with a more recent zed?
We revamped our environment loading in the intervening months and I think it may have solved this issue.
