What steps will reproduce the bug?

https://github.com/vjpr/issue-node-experimental-specifier-resolution

pnpm install
./index.sh

How often does it reproduce? Is there a required condition?

Pnpm relies on realpaths. Package managers relying on hoisting will not encounter this issue as they will eventually find the package hoisted.

This is why it was probably hard to detect.

What is the expected behavior?

Realpath should be called when --experimental-specifier-resolution=node is set.

What do you see instead?

It's not being called, and modules are resolved using logical paths.

Notice how realpathSync is not called if the --experimental-specifier-resolution=node option is set.
