>+        [Pointer Events] Respect pointer capture when dispatching mouse boundary events and updating :hover
>+        https://bugs.webkit.org/show_bug.cgi?id=198999
>+
>+        Reviewed by NOBODY (OOPS!).
>+
>+        Up until now, we would not account for pointer capture (see https://w3c.github.io/pointerevents/#pointer-capture) when dispatching
>+        mouse boundary events (mouseover, mouseout, mouseenter, mouseleave) and their counterpart pointer events. We would also not account
>+        for it when updating :hover styles.
>+
>+        Now, when pointer capture changes for an element, we call setCapturingMouseEventsElement() on the EventHandler such that the element
>+        that would naturally hit-test is overridden by the pointer capture element when identifying which target to use for the dispatch of
>+        boundary mouse events. Additionally, when calling EventHandler::prepareMouseEvent(), we also use the pointer capture element to
>+        eventually pass down to Document::updateHoverActiveState() such that :hover styles are applied to the correct element.
>+
>+        This also means that we need to re-run EventHandler::prepareMouseEvent() during mouse state changes to ensure that the :hover styles
>+        are applied correctly should the pointer capture element change during dispatch of boundary mouse events.
>+
>+        * dom/Document.cpp:
>+        (WebCore::Document::prepareMouseEvent): If there is one, use the pointer capture element instead of the hit-test target.
>+        (WebCore::Document::updateHoverActiveState): Relax the mustBeInActiveChain condition in case the pointer capture element changed when
>+        updating the :hover/:active chains.
>+        * page/EventHandler.cpp:
>+        (WebCore::EventHandler::handleMousePressEvent): Re-process the mouse event if the pointer capture element changed during event dispatch.
>+        (WebCore::EventHandler::handleMouseMoveEvent): Re-process the mouse event if the pointer capture element changed during event dispatch.
>+        (WebCore::EventHandler::handleMouseReleaseEvent): As we know the pointer capture element will be reset as part of the mouse being
>+        released, we reset the pointer capture element and EventHandler's capture element prior to invalidating hover styles and boundary events.
>+        (WebCore::EventHandler::setCapturingMouseEventsElement): Dispatch boundary events when a new element is set.
>+        (WebCore::EventHandler::dispatchMouseEvent): New dispatchMouseEvent() variant that re-processes the provided MouseEventWithHitTestResults
>+        in case the pointer capture element changes during event dispatch, as called by handleMousePressEvent() and handleMouseMoveEvent().
>+        * page/EventHandler.h:
>+        * page/PointerCaptureController.cpp:
>+        (WebCore::PointerCaptureController::pointerCaptureElement): We now need to query whay the pointer capture element might be from EventHandler,
>+        so expose a new method to access it.
>+        (WebCore::PointerCaptureController::hasPointerCapture): We would mistakenly return true if the provided element was null, which could be the
>+        case of EventHandler's capturing element. Rather than changing call sites to check that the provided value exists, we change the method to
>+        return false when the provided element is null. Note that this does not affect the API since it's exposed on Element itself.
>+        (WebCore::PointerCaptureController::processPendingPointerCapture): Make sure this method is not re-entrant since it dispatches events.
>+        * page/PointerCaptureController.h:
>+        * rendering/HitTestRequest.h:
>+        (WebCore::HitTestRequest::pointerCaptureElementChanged const): Add a new HitTestRequestType bit such that we can indicate to Document::updateHoverActiveState()
>+        that it must be update the :hover/:active chains when the pointer capture element has just changed.
