[Bug]: Jest with TypeScript, ES modules and bundler moduleResolution cannot find additional modules

[ahtokca]

Version

29.7.0 / 30.0.0-alpha.7

Steps to reproduce

1. clone my repo at https://github.com/ahtokca/jest-module-not-found
2. pnpm i
3. jest
4. you should see the error come up

Expected behavior

I expect the jest resolves the module and test passes as tsx --tsconfig tsconfig.json src/sub-entry.ts does

Actual behavior

Jest throws the error below:

Cannot find module 'custom-dependency/sub-entry' from 'src/sub-entry.spec.ts'

at Resolver._throwModNotFoundError (node_modules/.pnpm/jest-resolve@29.7.0/node_modules/jest-resolve/build/resolver.js:427:11)
at Object.<anonymous> (src/sub-entry.spec.ts:4:34)

Additional context

Jest is not able to resolve the module path correctly when using "bundler" as the
module resolution strategy. It seems jest relies on naming convention "module-name.{d.ts|js}", so if module has a custom
naming in exports then jest tests will fail to discover the module.
