Add a missing dispatch

[ChrisRackauckas]

@avik-pal this needs fmap and thus a Functors.jl dependency. Could that be avoided somehow or is it necessary? I would guess you could turn it into a componentarray and then apply backing?

Functors is an extremely lightweight dependency (it literally just depends on LinearAlgebra).

I would guess you could turn it into a componentarray and then apply backing?

That was my first attempt. But Tangent is not an AbstractArray so CA wouldn't flatten it.

That should be fine, then.

This should be good to go now. Fixes the last bug in https://github.com/SciML/SciMLSensitivity.jl/pull/818
