After extending web_sys with an IDL, when running` cargo doc --all-features --open` I get an erroneous can't find type error

[Sam Judelson]

Describe the Bug

When I run
cargo doc --all-features --open
on this crate
https://github.com/sjud/wasm-bindgen/tree/fedcm_idl
which is the result of running
cargo run --release --package wasm-bindgen-webidl -- webidls src/features ./Cargo.toml
after adding this idl
https://github.com/sjud/wasm-bindgen/blob/fedcm_idl/crates/web-sys/webidls/unstable/FedCM.webidl

I get this error

error[E0412]: cannot find type `IdentityCredentialRequestOptions` in this scope
  --> crates/web-sys/src/features/gen_CredentialRequestOptions.rs:15:61

5  | #[wasm_bindgen]
   | --------------- similarly named struct `CredentialRequestOptions` defined here

For more information about this error, try rustc --explain E0412.
error: could not document web-sys

Except, this is wrong because
https://github.com/sjud/wasm-bindgen/blob/fedcm_idl/crates/web-sys/src/features/gen_IdentityCredentialRequestOptions.rs
exists and is in the mod.rs
https://github.com/sjud/wasm-bindgen/blob/fedcm_idl/crates/web-sys/src/features/mod.rs
line 4763

Steps to Reproduce

1. Clone the repo https://github.com/sjud/wasm-bindgen
2. Switch to branch fedcm_idl
3. run cargo doc --all-features --open

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

Expected Behavior

No type not found error.

Actual Behavior

There is a type not found error.
