+     * 2) The planes don't changes color when hovered initially
+     * 3) Putting something in the scene makes the planes hidden
+     * 4) Removing everything from the scene shows the plans again
+     * 3) Once "start sketch" is click, the planes do respond to hovers
+     * 4) Selecting a plan works as expected, i.e. sketch mode
+     * 5) Reloading the scene with something already in the scene means the planes are hidden
