I guess we should do the same for mouse wheel events.

Since we now do this conversion in each of the dispatch functions, do you want
to extract this into a helper function? Maybe one that returns
ScreenPositionClient*?

Done.

   ui::EventType event_type = WebMouseEventTypeToEventType(web_mouse.type);
   int flags = WebMouseEventButtonToFlags(web_mouse.button);
-  // TODO: last argument (changed_button_flags) likely isn't right.
-  ui::MouseEvent mouse_event(event_type, location, location, flags, 0);
+  ui::MouseEvent mouse_event(event_type, location, location, flags, flags);
 
   GetRootWindowHostDelegate()->OnHostMouseEvent(&mouse_event);
