Treegraph collapsed nodes hover shows tooltips for its hidden children.

[ddragula]

Expected behaviour

When a node in a tree chart is collapsed, its hidden children should not respond to hover and their tooltip should not be displayed at any time.

Actual behaviour

When we hover and move the mouse over the label of a collapsed parent, the tooltips of its hidden children will appear.
