--- Comment #4 from Carlos Garcia Campos <cgarcia at igalia.com> ---
One problem we have in X11 is that mouse events are not always processed in the order they are sent. The main difference is that when the context menu is shown, a crossing event is generated in the web view, a leave happens in the view and enter in the context menu. That crossing is processed during the press:

1- ButtonPress is received in the web process
2- handleContextMenuEvent()
3- MouseMove is received in the web process
4- DidReceiveEvent for the MouseMove is sent to the UI process
5- DidReceiveEvent for the ButtonPress is sent to the Ui process

This breaks the queue model used in the UI process.
