Inline assistant outputs Elm code with shifted indentation under certain conditions

Summary

Inline assistant outputs Elm code with shifted indentation under certain conditions

Steps to trigger the problem:

1. Write a minimal Elm function that has no doc comment above its signature
2. Select the body of the function
3. Ask the inline assistant to make an edit

Actual Behavior: The generated code is offset to the right (making the module invalid Elm code!)

Expected Behavior: The generated code should preserve the original indentation

This also seems to happen if the function has a doc comment the selected range contains the comment. This doesn't seem to happen if the function has a doc comment but the selection does not include it. Attaching a recording below.

My settings.json is really minimal (I started using Zed very recently), and I don't suspect anything there might cause this. I am observing this with both Zed and OpenAI as AI providers. This also happens regardless of whether I am using elm-language-server or not, or where I have format_on_save enabled or not.
