C4DtoA | Shadow catcher plane visible with atmosphere volume

[led_stereo]

In the attached render, I'm using a quad light to light the scene, a Shadow Matte on the ground plane and an Atmosphere Volume. When the Atmosphere Volume is added, the edge of the shadow catcher plane becomes visible. How is this avoided please? Thanks for any pointers.

Seems like a bug. While it's fixed, a workaround could be to use a box type Arnold Volume object scaled up as a volume container around the scene with a standard_volume shader, instead of the atmosphere_volume.
