Bug report #9918
Enable the button to add new symbol layers (not only when the marker entry is selected)

Currently, the user can only add a new symbol layer after first selecting the marker entry from the tree list.
I think it's safe enough to allow adding symbol layers also when another entry is active in the tree list. The logic could be: If the currently active symbol level does not support adding levels, add them to the parent.
