Gizmos only work on last created scene

Hi all,

You can see it in the playground below. The gizmos work fine in the right scene (scene2, which was created last), but for the left scene, the gizmos appear in the right scene, and they don't work! If you crate the right scene before the left one, the behavior is switched.

@trevordev do you know what's going on here? And thanks for making the gizmos, can't wait to use them!
