       And I am working in the timeline "Storyboard" of the project called "Space Pilot 3000"
      When I go to the page of the timeline of the project called "Space Pilot 3000"
       And I show only work packages which have the type "Milestone"
       And I wait for timeline to load table
      Then I should see the work package "Hubert Farnsworth's Birthday" in the timeline
       And I should see the work package "Mission to the moon" in the timeline
-      And I should not see the work package "Space Pilot" in the timeline
+      And I should not see the work package "Unrelated" in the timeline
