Steps to reproduce:

1. Configure (set a css goal) and start a test
2. Edit the test and try to change the original page and the goal

Expected results:

• Setting a new original page should not be allowed
• Setting a new goal should not be allowed
• Configured goal should be highlighted

Actual results:

• You can save the running test with a new original page and a new goal
• In the goal selection dialog, depending on the dispatcher, the original page is not shown, only the variant
• The configured goal is not highlighted
