SSM GUI doesn't highlight the current state

[hsd-dev]

I have observed this behaviour especially while running moveit related states. Whenever the arm is moving, the previous state is still highlighted. Only after the completion of movement, the current state is highlighted. Is this related to threading somehow? Or it is an expected behaviour?

Thanks

This is related to threading because there is a single thread spinner and the update of the visual actually works with a callback. I will figure out a way to solve that.
