Parcel fails to build with Transformers.js v3

🐛 bug report

Parcel fails to build with Transformers.js v3.

🎛 Configuration (.babelrc, package.json, cli command)

See all details in Bug repro repository.

• No .babelrc
• package.json
• cli command: npm run dev

🤔 Expected Behavior

Parcel builds successfully.

😯 Current Behavior

Parcel fails to build.
Error: "@parcel/core: Failed to resolve '#onnxruntime-webgpu' from './node_modules/@huggingface/transformers/src/backends/onnx.js'"

See Bug repro repository.

💁 Possible Solution

Not a full solution, but a few pointers:

• #onnxruntime-webgpu resolution should be handled by Transformers.js: getModelJSON fails with a bundler (see reproduction) huggingface/transformers.js#366 (comment)
• It appears that the Vite bundler doesn't have this issue. Here's a repro of Vite building successfully: https://github.com/maudnals/vite-transformersjs3.

🔦 Context

I encountered this issue while trying to upgrade the Transformers.js version in my Parcel-bundled demo.
Transformers.js v2 worked fine with Parcel (modulo one issue, which is likely a different one - Details here).
