How can I force the FramingTransposer to damp its roll axis?

When using a FramingTransposer Body component with a Composer Aim component (still working on the Souls-like lock-on camera), if the Body’s transform passes through the LookAt transform (in the camera plane), the two components are forced to spin the camera around the z-axis to correct the framing. Because there is no parameter for damping roll on either Component, it causes incredibly jerky and erratic camera movement. Is there a modification I can make in the component code or an extension I can include that will force the vCam to correctly damp in this situation?

I was able to trivially reproduce the issue I’m seeing in the Cinemachine samples by disabling the Y-locking and tweaking the BossCam with framing more appropriate for a genre using this style. If the player is allowed to jump on/over its target, the camera breaks.
