Description

I've got a bit of a challenging one here. It's hard to trace the issue because I don't have debug information available from SpiderMonkey (will traces from the engine be available via some debug mode at some point?)

I have a repro but it requires my toolchain. Shouldn't take long to set up:

1. Grab the latest `rune-cli` release from https://github.com/rune-runtime/rune/releases/tag/v0.1.11 (or use `curl -fsSL https://rune.sh/install.sh | bash` to install `rune` locally) -- I think you'll need a Mac for this for the time being.
2. Create a new directory, ie. `test` & cd into it
3. Run `rune new game --template cube-js` -- this will create a new Rune project in the current directory
4. Run `npm i`
5. Run `rune run`. Observe that the program crashes with [1]
7. In `game.js`, comment out line 194 and `rune run` again. Observe the program does not crash.

This invocation, `pipeline.getBindGroupLayout(0)` works in my Rust wasm32-wasip1 guest module (you can try it by doing `rune new game --template cube-rust`) Because of this, I believe there is a bug in ComponentizeJS. Without better debugging I can't say for certain.

If you need to debug the use of ComponentizeJS in my toolchain, you should refer to the module in `node_modules/@bytecodealliance/ComponentizeJS`, which is used by the `@rune-runtime/rollup-plugin-rune` Rollup plugin to build a wasm module for Rune.

Guidance is appreciated. Thanks.
