            Bug ID: 216149
           Summary: Promises created from async functions don't resolve
                    when document is detached.
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: john.david.dalton at gmail.com

The following snippet works in Chrome:

(async () => {
  var i = document.createElement('iframe');
  document.body.appendChild(i);
  var a = i.contentWindow.eval('(async () => await 1)');
  i.remove(); // someone removes the iframe
  const v = await a();
  console.log(v);
})();

Our use case has code that works when wired up and then someone removes the iframe and `await` no longer resolves.
