Describe the Bug

A clear and concise description of what the bug is.

Steps to Reproduce

1. checkout https://github.com/lizelive/wasm-bindgen/blob/4bf006d408f1244800156eb8b531366740af6595/crates/web-sys/webidls/unstable/WebNN.webidl
2. build podman run --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp/crates/web-sys mcr.microsoft.com/devcontainers/rust:1 cargo run --release --package wasm-bindgen-webidl -- webidls src/features ./Cargo.toml

If applicable, add a link to a test case (as a zip file or link to a repository we can clone).

Expected Behavior

should compile

Actual Behavior

Error: compiling WebIDL into wasm-bindgen bindings in file "webidls/enabled/CanvasRenderingContext2D.webidl", line 368 column 3

Caused by:
    failed to parse webidl at byte position 83817

Additional Context

you can work around by doing a typedef [EnforceRange] unsigned long Index32;
