UI: Activation Groups Menu not updating

Steps to reproduce:
1. Create new craft
2. Add another command pod to the default one
3. Rename an action group (or make any other change to make it distinguishable from the action groups of the other Pod)
4. close the side menu
5. select one Pod
6. open Action Groups in side menu
7. select the other Pod
8. observe behaviour: not viewing the Action Groups of the NEW-selected Pod
9 Workaround: change side menu category i.e. to Adding Part and back to Action Groups again
