Create Start -> End process
Select Sequence flow and check the Execution section
Actual Result:
Execution section will be shown, but it doesn't do anything for this case.
Expected Result:
Execution section should be hidden if sequence flow is after any node type but Exclusive and Inclusive Gateway.
Hide Graphical Constraint Editor if sequence flow is after any node type but Exclusive and InclusiveGateway (for parallel gateway this property also should be hidden).
