Can you move this entirely into AshWindowTreeHostOzone? i.e.

// ui/aura/window_tree_host_ozone.h
void DispatchEvent(ui::Event* event) override;

// ui/aura/window_tree_host_ozone.cc
void AshWindowTreeHostOzone::DispatchEvent(ui::Event* event) {
  if (event->IsMouseEvent() || event->IsScrollEvent())
    TranslateMouseEvent(static_cast<ui::LocatedEvent*>(event));
  SendEventToProcessor(event);
}

+    TranslateLocatedEvent(static_cast<ui::LocatedEvent*>(event));
   SendEventToProcessor(event);
 }
 
 void WindowTreeHostOzone::OnCloseRequest() {
   OnHostCloseRequested();
 }
 
 void WindowTreeHostOzone::OnClosed() {
