Description
A wasm2js-transpiled JS module is throwing an error after an async call, but the WASM binary is working just fine. The wasm binary is compiled from a rust crate using wasm-bindgen and then built with wasm-pack. For some context, this async call is to a Rust function that then makes a async call back into JS before returning.
The error in particular is
# Unhandled error between tests

To be clear, the code after the async function still runs, so this seems to be happening async somewhere. Adding a debug statement to this finally block I can see, export 3, which is the function table, is indeed undefined.
In makeMutClosure {
export3: undefined,
