Steps to reproduce the problem

1. Change https://github.com/mozilla/pdf.js/blob/master/test/unit/pdf_spec.js#L142 from it to fit.
2. Run npx gulp unittest and notice that the test passes.
3. Run npm install webpack@5.99.0 (or higher; as of writing everything until the most recent 5.99.5 version is broken)
4. Run npx gulp unittest and notice that the test fails with globalThis.pdfjsLib being undefined:

TEST-UNEXPECTED-FAIL | checks that the viewer re-exports the expected API functionality | in firefox | TypeError: globalThis.pdfjsLib is undefined in http://127.0.0.1:43601/web/pdfjs.js (line 67) 
TEST-UNEXPECTED-FAIL | checks that the viewer re-exports the expected API functionality | in chrome | TypeError: Cannot destructure property 'AbortException' of 'globalThis.pdfjsLib' as it is undefined

What is the expected behavior?

The test should pass after the Webpack update.

What went wrong?

The test fails after the Webpack update.

Additional context

It looks related to webpack/webpack#19394, but that was closed and I can't find other reports about similar issues. We should probably try to create a reduced test case that we can report upstream for this since it might be another case of that issue.
