typescript intellisense can't find second level index.ts

Bug Report

it's reopening of #42247 as tested what was suggested and didn't work, opening it as I didn't get any more comment on that issue

https://github.com/microsoft/TypeScript/issues/42247#issuecomment-758863988

Auto-import assumes that an index.d.ts that re-exports a bunch of stuff is a "barrel" module that intends to provide a facade over an opaque directory hierarchy. So in that case, if you want the deeper path, you'd need to just import "./platform-browser/animations"; instead of re-exporting those members.

I tried @RyanCavanaugh suggestion but look like it doesn't work

⏯ Playground Link

I created two repos, one following the suggestion and another one with normal index.ts

each repo has a gif showing that IntelliSense doesn't work!

https://github.com/mhamri/vscode-typescript-intellisense-bugs/tree/main/nx-lib-second-level-index-ts

and here is a repo of normal index.ts that still with path doesn't get discovered

https://github.com/mhamri/vscode-typescript-intellisense-bugs/tree/main/nx-lib-first-level-index-ts

🙁 Actual behavior

should get suggestions and IntelliSense for the first level and second level items. or typescript suggests a way that works. atm typescript doesn't give any IntelliSense for any of the second level index.ts for libraries like RxJs , Angular

Please check the original issue, more links to other repos are attached.

🙂 Expected behavior

typescript provides suggestion for the second level items.

Start by reproducing the behavior in the two linked repositories, then read the referenced comment and issue #42247 for the prior investigation. Done means determining whether TypeScript can provide first- and second-level index.ts IntelliSense suggestions, or documenting a supported import pattern that works.
