What happened?
In the demo of the app, https://resources.jointjs.com/demos/visio-bpmn-export on exporting the diagram, the end event shape does get exported but the shape representation is incorrect. It is that of intermediate event although the type is correct. Please see the screenshots below for further explanations.



Just FYI, this is the correct representation of End Event in Visio.
