Self-reference dependency has unused export name when imported inside of a web worker

[pgoldberg]

Bug report

What is the current behavior?

When a web worker imports a CommonJS module with a self reference dependency, webpack throws Error: Self-reference dependency has unused export name: This should not happen.

This happens when usedExports is set to "global".

I think this is related:
#12646 / #12648

It seems like that fix works when usedExports is not set to "global", but it doesn't work when usedExports: "global" is set.

If the current behavior is a bug, please provide the steps to reproduce.

What is the expected behavior?

Webpack should not throw an error
