• VSCode Version: 1.52.1
• OS Version: Windows 10.0.19042.685

Steps to Reproduce:

1. Create a HTML File with <script type="module">...</script>
2. Add // @ts-check and import any npm package
3. No intellisense

Does this issue occur when all extensions are disabled?: Yes

If we would do the same steps with a .js file, IntelliSense will work:

It is not working in .html however:

Error:
Cannot find module 'hydro-js'. Did you mean to set the 'moduleResolution' option to 'node', or to add aliases to the 'paths' option?javascript

Tried troubleshooting:

1. Created a jsconfig.json file
2. Tried the above error suggestions.
