using prep for out of place method?

Hi,

This is probably trivial to you but it does not work

backend=DI.AutoForwardDiff()
F(x) = x
prep=prepare_jacobian(F, AutoForwardDiff(), zeros(2))
DI.jacobian(F, backend, zeros(2)) # works
DI.jacobian(F, prep, backend, zeros(2)) # does not work

For me both work, with the proper imports. Can you share your stacktrace? I suspect you might still be on DI v0.5

it was 0.5.9, it works for me now, thank you
