"Inline Subdiagram"-Refactoring during simulation leads to inconsistent highlighting

[atasman]

The model to produce the issue was build the following way:

1. Create a new file
2. Insert a second state ("StateB")
3. Insert 2 transition between "StateA" and "StateB" in each direction with valid triggers (e.g every 5s)
4. Select both states and execute "Group States into Composite"in the Refactor context menu
5. Select Composite State and "Extract Subdiagram"
6. Run Simulation

Reverting this during simulation by doing the Undo action or the "Inline Subdiagram" action will lead to inconsistent highlighting. (see figure)

The correct behaviour would be highlighting the composite state and one of the states inside the composite state
