… flags This flag was originally added in emscripten-core#16813 to test WasmFS OPFS support, which has shipped in stable Chrome since version 102. In Chrome 154, `--enable-experimental-web-platform-features` enables `AudioWorklet.port` (https://crbug.com/446920095). However, Chrome cannot deserialize `WebAssembly.Module` over a `MessagePort` into `AudioWorkletGlobalScope` (https://crbug.com/40210558). This causes Emscripten's feature check in `src/lib/libwebaudio.js` to skip the `em-bootstrap` AudioWorkletProcessor and attempt to transfer the Wasm module over `audioWorklet.port`, triggering a `messageerror` and breaking all audio worklet tests in Chrome 154.
