Workaround

The IsFlattened property must be manually changed from True to False. The layer object's Cartographic Information Model (CIM) can be overwritten to modify this property. As soon as the IsFlattened property is changed from True to False, the layer is moved from 2D layers to 3D layers in the Contents pane for the Scene.

lyr = m.listLayers('<Polygon Layer Name Here>')[0]

lyr.extrusion('BASE_HEIGHT', 150)

lyrCIM = lyr.getDefinition('V2')

lyrCIM.isFlattened = False

lyr.setDefinition(lyrCIM)
