15b6 Compound Clip Transform applied to Clip below (Bug?)

Hello,
a CompoundClip with one UltraKeyer FusionClip inside has Transform set for Zoom, Position,Rotation,Pitch and Yaw.
The background plate on Track Video 1 gets the Transform settings of the CompundClip applied.

Moving the background plate to another point on the timeline without a clip on top, shows the footage without transform as expected. Only when putting it under the CompoundClip it receives the transform settings from that clip above.

Is this a bug or am I missing something?

Thanks,

I think it's intended, since a compound is explicitly meant to change the processing pipeline for Fusion (page 2-54 in the current version of the new manual).

Thanks Uli,
if this behavior is really intended, do you know a way to leave the clip below the compound unaffected?
I need this as a background plate as-is.

Thanks,
