Wasm es6 modules fail to load with Jest, but work in Node

🐛 Bug Report

I’m able to load an es6 module with Node, but I’m unable to load the same module when running with Jest. When I try loading the module with Jest, I get the following error:

node --experimental-modules --experimental-wasm-modules --experimental-vm-modules node_modules/.bin/jest

(node:72954) ExperimentalWarning: VM Modules is an experimental feature. This feature could change at any time (Use node --trace-warnings ... to show where the warning was created) FAIL tests/test_jest.test.mjs ● Test suite failed to run

/Users/me/projects/bin_packing/jest-wasm/node_modules/bin_packer_3d/bin_packer_3d_wasm_bg.wasm:1
({"Object.<anonymous>":function(module,exports,require,__dirname,__filename,global,jest){


SyntaxError: Invalid or unexpected token

  at Runtime.createScriptFromCode (node_modules/jest-runtime/build/index.js:1350:14)

To Reproduce

Steps to reproduce the behavior:

1. Clone this repo: https://github.com/modulitos/jest-wasm-esm-example
2. run npm run test-jest

Note that running npm run test-node loads the module successfully in Node. So why does it fail with Jest?

Expected behavior

The module loads when running npm run test-jest.

Nice! Just tested 29.3.0 against the same demo project and it worked without a local patch! 🎉
