The steps of event dispatch post-processing (https://cs.chromium.org/chromium/src/third_party/WebKit/Source/core/dom/events/EventDispatcher.cpp?sq=DispatchEventPostProcess&l=25) is not in the same order as in the spec (https://dom.spec.whatwg.org/#concept-event-dispatch).

Expected:
The event dispatch steps are done in the same order as the spec.

Actual:
In the current code, "Set event’s currentTarget attribute to null." is done before "If target's root is a shadow root, then set event’s target attribute and event’s relatedTarget to null.". Naively moving the step to the right order results in test failures.
