Working on the issue.

I just found one more bug related to Expensify/react-fast-pdf#30. The problem is replicable on the latest package version. However, I can see that the package version in the example is pretty old - 1.0.2 while the current is 1.0.21. I am going to upgrade the package version and fix the bug. Basically, it conflicts with styles.

After investigations, I've found only one combination that works with IOS 17.x. It is the legacy PDF worker. Moreover, it must be unminimized - pdfjs-dist/legacy/build/pdf.worker.mjs.

No overdue. I am actively working on the issue.
