the "Is Visible" node does not appear to consider the visibility of any parent widgets

When using the "Is Visible" node for a widget who parent is set to hidden, the node will return true even though the widget cannot be seen.

1. Open the editor
2. Create a new widget blueprint
3. Add an image to the canvas panel
4. Set the visibility of the canvas panel to hidden
5. Create the blueprint in the attached image
6. Play in editor

Result: The is visible node will return true for the image even though the image is not visible on screen (because its parent is hidden)
Expected: The is visible node would return whether or not the widget is currently visible
