ReferenceError: Cannot access 'index' before initialization at fontkit\lib\fontkit.cjs.js:36896:21

Describe the bug
Generating PDF on a server with custom opentype font throws an error.

To Reproduce

1. Clone https://github.com/t-ondrej/reactpdf-otf-bug
2. Run npm run dev
3. Open http://localhost:3000
4. See error in server console

If you switch font to 'Pecita' (TestDocument.tsx:3) you'll get similar error (ReferenceError: Cannot access 'set' before initialization) from other place.

Expected behavior
Custom opentype fonts are loaded without any issues

Desktop (please complete the following information):

• OS: Windows
• Browser: Chrome
• @react-pdf/renderer@2.0.21

For the index related error, declaration is missing in

react-pdf/packages/fontkit/src/glyph/CFFGlyph.js

Line 308 in b536a2e

index = stack.pop() + gsubrsBias;

and here as well

react-pdf/packages/fontkit/src/glyph/CFFGlyph.js

Line 309 in b536a2e

subr = gsubrs[index];

For the set related error, declaration is missing in

react-pdf/packages/fontkit/src/opentype/OTProcessor.js

Line 367 in 416d08c

set = table.classSet[index];

Experiencing the same and as it seems this might be a node-specific bug since I'm rendering on nodejs without success, while using the same exact font on https://react-pdf.org/repl seems to work. That being said I've never been able to make a woff2 font work at all, neither in repl nor in node, although the underlying foliojs/fontkit should technically accept it.
