Description

I wrapped up an MWE in ImplicitAD.jl for an rrule I defined (see the single test). My issue is that

test_rrule(one_one, 1.0;
                   check_inferred = true,
                   fdm = forward_fdm(5, 1),
                   atol = ϵ, rtol = ϵ)

gives an inference failure, while

@inferred rrule(ChainRulesTestUtils.TestConfig(), one_one, 1.0)

is fine.
