Errors should move when editing the document

[erikschul]

After editing a document, the errors will still show on the previous line number, instead of moving.

Would it be possible to detect line changes and shift the errors?

Example: before

Example: after
Expected: error should show on line 17

I would need steps to reproduce the issue (to fix). Decorations usually follow errors properly.

@erikschul I believe this is a rust-analyzer issue. This happens when rust-analyzer executes cargo check and reports the errors in the UI. Then, when editing the file, rust-analyzer only has the old cargo check results to work with.
