Compile problem with wasm32 using bracket-terminal 0.8.7

I'm pulling bracket-terminal into my project as a dependency and compiling for wasm:

```
rustup target add wasm32-unknown-unknown
cargo install wasm-bindgen-cli
cargo build --release --target wasm32-unknown-unknown
```

I'm seeing the new errors:

```
