Close #39348 Now `NgZone` has an option `shouldCoalesceEventChangeDetection` to coalesce multiple event handler's change detections to one async change detection. And there are some cases other than `event handler` have the same issues. In #39348, the case like this. ``` // This code results in one change detection occurring per // ngZone.run() call. This is entirely feasible, and can be a serious // performance issue. for (let i = 0; i < 100; i++) { this.ngZone.run(() => { // do something }); } ``` So such kind of case will trigger multiple change detections. And now with Ivy, we have a new `markDirty()` API will schedule a requestAnimationFrame to trigger change detection and also coalesce the change detections in the same event loop, `markDirty()` API doesn't only take care `event handler` but also all other cases `sync/macroTask/..` So this PR add a new option to coalesce change detections for all cases. test(core): add test case for shouldCoalesceEventChangeDetection option Add new test cases for current `shouldCoalesceEventChangeDetection` in `ng_zone.spec`, since currently we only have integration test for this one. PR Close #39422
