Library seems to no longer work

[Nub]

It seems as if this library no longer functions. Tested the following in Chrome + Safari.

After integrating into my main application with no success, with the minimal usage of

    thread::spawn(|| {
        info!("HELLO WORLD");
    }).join().expect("HELLO BOOM");

causing the following error

/Users/zachthayer/.cargo/registry/src/index.crates.io-6f17d22bba15001f/wasm_thread-0.3.0/src/wasm32/mod.rs:349:10:
called `Result::unwrap()` on an `Err` value: JsValue(DataCloneError: Failed to execute 'postMessage' on 'Worker': #<Memory> could not be cloned.
Error: Failed to execute 'postMessage' on 'Worker': #<Memory> could not be cloned.

I then cloned this repo and ran the example test project and get the following

simple.js:306 panicked at src/wasm32/mod.rs:349:10:

What HTTP server are you using? The error indicates problem with cross origin isolation. The instructions in README use sfz server with --coi option to bypass this protection.

It works fine for me, and that error clearly shows that its not crossOriginIsolated.
