Unwanted auto-imports in script files

Bug Report

I have a mixture of module and non-module code.
The problem occurs when I edit non-module files (tsconfig: "module": "none").

Sometimes when using auto-completion (in VisualStudio 2022) typescript finds a "matching" name from the module world and adds a line like

import { HmiHelper } from './helper/HmiHelper.js';

into the first line of my file.
But as the current file was configured as "module": "none" this import pushes typescript into modules mode and the current code is invalid.
