+- As an alternative, you could pass to the `core-js/configurator` an object that will be considered as `%AsyncIteratorPrototype%`:
+```js
+const configurator = require('core-js/configurator');
+const { getPrototypeOf } = Object;
+
+configurator({ AsyncIteratorPrototype: getPrototypeOf(getPrototypeOf(getPrototypeOf(async function * () { /* empty */ }()))) });
