What steps will reproduce the bug?

• quibble
• esmock

both require to set a --loader option when starting node. Currently, my project uses both e.g. node --loader=quibble --loader=esmock. However, it seems that the latter option overwrites the first.

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

What is the expected behavior?

The expected behavior is that I can use multiple loaders, I guess.

What do you see instead?

I see that one loader is overwriting another, here's an error message thrown in a test because the loader quibble hasn't been respected.

 Error (NodeError) {
    code: 'ERR_MODULE_NOT_FOUND',
    message: 'Cannot find package \'cross-fetch?__quibbleresolvepath\' imported from /home/runner/work/project/project/node_modules/quibble/lib/esm-import-functions.js',
  }

It's currently not possible to chain loaders. This is tracked in #36396.
