error on init (__wbindgen_cb_forget)

[derekdreery]

Describe the Bug

In browser the wasm fails to load with:

LinkError: import object field '__wbindgen_cb_forget' is not a Function

Steps to Reproduce

1. Update wasm-bindgen-cli and wasm-pack to latest release
2. git clone https://github.com/derekdreery/dodrio-realworld-starter-kit
3. cd dodrio-realworld-starter-kit
4. wasm-pack build --target web
5. python -m http.server (or your fave static file server)
6. go to http://localhost:<your_port>

Expected Behavior

You see a web page with some stuff in it

Actual Behavior

A blank page plus the aforementioned error message.

Additional Context

I tried adding in the export of __wbindgen_cb_forget manually and it all works then! So I guess the error is to do with it not getting exported. I tried to understand the code and failed.
