In the skill specialization menu, If you maintain alt and hover over nodes that add a spell ( e.g Essence of control or Spark charges in the mana strike specialization ) the tooltip of the spell (e.g Spark Charge / Lightning ) anchors to the right of the previously hovered node tooltip. It should anchor to the right of the currently hovered node tooltip.
On a side note ( should be a separate bug report but i’m lazy ), the tooltip for the Lightning spell is missing from the mana storm node of the Mana Strike skill specialization ( it appears correctly on the subsequent nodes )
