Bug 1637454 [wpt PR 23554] - De-flaky pointerevent_releasepointercapture_invalid_pointerid.html, a=testonly

Automatic update from web-platform-tests
De-flaky pointerevent_releasepointercapture_invalid_pointerid.html

Because of Linux memory leak, pointerevent wpt tests
pointerevent_releasepointercapture_invalid_pointerid.html is flaky, we
should finish the test in the actions promise's callback to guarantee
the actions are all executed before the test finishes to avoid memory
leak.
