//   1. 'disabled' - not enabled by the default flags.
//   2. 'nightly' - must be enabled in nightly and not release or beta.
//   3. 'released' - must be enabled in nightly, release, and beta.
//   4. 'released-maybe-disable' - should be enabled, but may not be supported
//      on a platform.
//
// As features are advanced, this test must be manually updated.
//
// NOTE1: This test relies on feature functions accurately guarding use of the
//        feature to work correctly. All features should have a 'disabled.js'
//        test to verify this. Basic testing for this is included with each
//        feature in this test for sanity.
// NOTE2: Keep this file in sync with:
//        `dom/worklet/tests/worklet_audioWorklet_WASM_features.js`.
