Ideally, the pref and complicated dispatchers will be removed/updated in
m-c on end of July unless nobody can work on it at that time. See bug
1904279 <https://bugzilla.mozilla.org/show_bug.cgi?id=1904279>.

Note that the behavior is switchable with a new pref,
|`dom.w3c_pointer_events.dispatch_click_as_pointer_event`|. Therefore,
for a while, new event dispatchers in C++ need to do:
Maybe<WidgetPointerEvent> pointerEvent;
Maybe<WidgetMouseEvent> mouseEvent;
if (StaticPrefs::dom_w3c_pointer_events_dispatch_click_as_pointer_event()) {
pointerEvent.emplace(true, ePointerClick, widget);
} else {
mouseEvent.emplace(true, ePointerClick, widget, WidgetMouseEvent::eReal);
}
WidgetMouseEvent& mouseOrPointerEvent =
pointerEvent.isSome() ? pointerEvent.ref() : mouseEvent.ref();
mouseOrPointerEvent.mSomething = something;
widget->DispatchInputEvent(mouseOrPointerEvent);
and chrome script and mochitest in chrome context need to do:
const ClickEventConstructor = SpecialPowers.getBoolPref(
"dom.w3c_pointer_events.dispatch_click_as_pointer_event"
)
? PointerEvent
: MouseEvent;
const clickEvent = new ClickEventConstructor("click", { bubbles: true,
cancelable: true, ... });
target.dispatchEvent(clickEvent);
