Description
Version: Deno 1.41.3
Reproduction: https://github.com/kylebarron/wasm-bindgen-deno-test
This exports a simple function panic_async. If you call this with await wasm.panic_async();,
the future never resolves and the REPL hangs forever:
Note that if you call the function without await then you do get an Uncaught RuntimeError
> wasm.panic_async();
Promise { <pending> }
Uncaught RuntimeError: unreachable

So I assume what's happening here is that constructing the future errors and then there's nothing to await, or something like that.
For contrast, running this in Node crashes the process:
To reproduce:
wasm-pack build --target web
Then inside Deno:
const wasm = await import("./pkg/wasm_bindgen_deno_test.js");
let _ = await wasm.default();
await wasm.panic_async();
