Sub-process cancelled by a boundary event is not clickable anymore

Failing scenario: deploy the two processes, "a" is a parent, "signal-alias-test" is a child. Start "a". View "a" in kie-server, navigation to sub-process works. Send signal "abort" to the "a" instance, so that it's completed. View "a" instance in kie-server again, the navigation to sub-process does not work anymore. Ok scenario: deploy the two processes, "a" is a parent, "signal-alias-test" is a child. Start "a". View "a" in kie-server, navigation to sub-process works. Send signal "child" to the child instance, so that it's completed. View "a" instance in kie-server again, the navigation to sub-process does still work correctly.
