TypeScript notebook cells can't find relative paths or tsconfig.json

[jaked]

Type: Bug

VS Code gives notebook cells "dynamic" paths (starting with e.g. ^/vscode-notebook-cell/ts-nul-authority) when communicating with tsserver, but TypeScript doesn't resolve relative imports from dynamic paths, and infers a config instead of using the appropriate tsconfig.json for the path. So notebook cells show errors on relative imports, can't use types from relative imports, and can have other errors because of config issues.

See also #196172

Here's a hacked-up TypeScript that handles these paths githubnext/TypeScript@v5.4.5...jaked/vscode-notebook-fixes but maybe TypeScript needs explicit support for URIs so VS Code can use them directly instead of overloading the dynamic path syntax?

I see that the insiders build has disabled semantic errors (#212366) but it would be better of course to fix the problem 🙂.
