Close #38863 Monkey patches `queueMicrotask()` API, so the callback runs in the zone when scheduled, and also the task is run as `microTask`. ``` Zone.current.fork({ name: 'queueMicrotask', onScheduleTask: (delegate: ZoneDelegate, curr: Zone, target: Zone, task: Task) => { logs.push(task.type); logs.push(task.source); return delegate.scheduleTask(target, task); } }).run(() => { queueMicrotask(() => { expect(logs).toEqual(['microTask', 'queueMicrotask']); expect(Zone.current.name).toEqual('queueMicrotask'); done(); }); }); ``` PR Close #38904
