source.organizeImports should not remove imports if file contains errors.

Bug Report

When a user has source.organizeImports enabled on save/blur, the imports are mistakenly removed if the file contains errors. It also happens file contains an unclosed block comment /* (for example, when the file got saved in the middle of writing a comment).

💻 Code

An example of a broken file. This example contains JSX, hover, the point here if the file IS broken, then we should not remove imports.

File: test.ts (NOT test.tsx)

import { uniq } from "lodash";

export default function useAssetTypeFilterOptions() {
  return (
    <input
      name="aaaaaaaaaaaaaaaaaaaaaaaaaaaa"
      value={uniq(["a", "b", "c"]).join(" + ")}
    />
  );
}

🙁 Actual behavior

• The imports are erroneously removed

🙂 Expected behavior

• The imports should not be removed if the source file contains errors.
