Bug report for start/stop button in engine testing

[jbajak]

Replication scenario:
1. In engine design go to TESTING
2. Click on 'Test Mode' to enter view which allows to set RPM manually
3. Click on circular red button with 'START!' label
4. Then click again on the same button (now has ''STOP!' label)
5. Button still has 'STOP!' label though engine is already stopped

Alternative replication scenario, starts after 3.:
4a. Click on any button from right side, e.g. 'BOTTOM END', 'TOP END', etc.
5a. Engine automatically stops.
6a. Go to TESTING again
7a. Button has wrong label - 'STOP!'

Expected behavior:
After engine stops, button should have 'START!' label.
