1.) create signavio connector with our camunda web modeler (vm2)
2.) create filesystem connector
3.) roundtrip file 'SUPPORT-781' from signavio through filesystem
After the roundtrip all extension elements are lost.
I also attached the following 2 bpmn files:
before_roundtrip: bpmn file export from our camunda web modeler
after_roundtrip: bpmn file from cycle roundtrip
