Expected behavior:

Actual behavior:

The project tries to compile a index.ts which imports @types/node. Internally @types/node has http module. TS then assumes that http module is http.ts in the current project and compiles it. I think that is incorrect behavior.

It is strange that a file in node_modules can control which files get compiled in my project. I think that once trace resolution enters node_module it should not be allowed to escape out of it.
