Deno fails with "NotSupported: Classic workers are not supported."

[jamsinclair]

Describe the bug
Using a multi-threaded supported module fails with:

NotSupported: Classic workers are not supported.

Reproduction

import encode from '@jsquash/avif/encode';

await encode(new ImageData(new Uint8ClampedArray(4 * 50 * 50), 50, 50));

Expected behavior
Should work without additional configuration.

Looks like this may be solved by emscripten-core/emscripten#20452 and emscripten-core/emscripten#20513 – newer versions of emscripten will compile workers with { type: 'module' } 🎉
