skeleton view is not notified of active node change

[Optiligence]

arrow rendering isn’t updated immediately (it is e.g. on hovering)

it’s not a big thing, so i wont do something about it now

To reproduce:

• select multiple nodes in skeleton view
• click on a selected (non active) node -> the arrow indicating the active node disappears (but reappears when the mouse leaves the marked row)
