We need to move EditorEventListener::HandleMiddleClickPaste() into EventStateManager to handle middle click paste after all click events are dispatched. This is preparation of the change. HandleMiddleClickPaste() uses UIEvent::GetRangeParent() and UIEvent::RangeOffset() to collapse Selection at clicked point. However, EventStateManager cannot access them since EventStateManager can handle it with WidgetMouseEvent. Fortunately, only WidgetMouseEvent is necessary for implementing them. Therefore, we can move the implementation into nsLayoutUtils and merge them. Differential Revision: https://phabricator.services.mozilla.com/D7851 --HG-- extra : moz-landing-system : lando
