Description

I've tried to use Zygote with ComponentArrays but cannot it cannot get through this code:

c = ComponentVector(a; b...)

I think it is just a missing ChainRule rule. I've tired, but unfortunately writing rules is black magic for me...

Research direction

Start by reproducing the failure with Zygote using ComponentVector(a; b...), then inspect the existing ChainRule definitions related to ComponentVector. Done means this construction differentiates successfully through Zygote without the reported error.
