Nested 3D Comp With CollapseTransforms Messes With Other Copies in 3D Container

I have a 3D comp with animation in it.

Now, if I nest several copies of this comp with collapsed transformations, then the very top layer influences the underlying copies, e.g. changing its time value (animated timeRemap, expression, or simply shifting the layer over time), makes all the underlying copies within the 3D container, use the time from the top one.

Am I missing anything essential about collapse transformations + time property?

Such behavior seems fundamentally abnormal, possibly a bug, however it should be tested by the other users, as it might be a local glitch.

Here I add a AEP file made of solids alone.

See yourself by shifting the "MOVE ME" layer on timeline back and forth. You can also try enabling randomization expressions in *T, *S, *E compositions, which will override the existing color animation and make it more obvious. Try adding AdjustmentLayer to split the 3D container, see how the mess spreads.

Please, report back if you experience same thing.

P. S. Closest to what I was experiencing was probably this post: https://community.adobe.com/t5/after-effects-discussions/time-remapping-issues-with-master-composition/m-p/10515439 which wasn't resolved.
