What about `gamma_inc_inv`'s derivative ?

Research direction
Start by locating the gamma_inc_inv and __gamma_inc_inv entry points and inspect how they handle ForwardDiff.Dual arguments. Determine whether derivative support is feasible for the inverse incomplete gamma routines; done means the reported MethodError is addressed with appropriate coverage.
Written by the indexing model from the issue text.
Description
I am hitting the following issue :
ERROR: MethodError: no method matching __gamma_inc_inv(::ForwardDiff.Dual{...}, ::ForwardDiff.Dual{...}, ::Bool)
Is there somewhere an implementation for such a derivative ? I guess the routines for the inverse of the gamma incomplete function are based on numerical root finding, so it that even possible ?
