The bug in 2D Plane

[iamcxds]

I am trying to create a 2.5D game and follow the example 2D Plane. Because I can move the plane in my game, I find there will be some bugs when vertical sprites go behind the screen.

To recreate this bug, change the y of squarePlane into positive so that it will be behind the screen, e.g
squarePlane.position.set(-app.screen.width / 4, app.screen.height / 2); . Then drag down the squareFar, and the sprite will come back from the sky.

Is there any way to avoid this feature?
