Bugzilla

This causes failure in https://searchfox.org/mozilla-central/rev/99f83e78415867726a5076a525e4a60840f3be33/testing/web-platform/meta/pointerevents/pointerevent_pointercancel_touch.html.ini#4

The error there is only about the order, but `pointercancel` happen at all, which you can confirm by adding the following:

```js
                on_event(target0, "pointerup", function (event) {
                    test_pointerEvent.step(function () {
                        // Never happens after pointercancel!
                        assert_unreached("No pointerup should happen");
                    });
                });
```

The error there is only about the order, but `pointercancel` doesn't happen at all, which you can confirm by adding the following:

```js
                on_event(target0, "pointerup", function (event) {
                    test_pointerEvent.step(function () {
                        // Never happens after pointercancel!
                        assert_unreached("No pointerup should happen");
                    });
                });
