Is there a way to NOT ignore current bindings when auto_bindings=True ?

class A:
    ...

class B:
    def __init__(self, a: A):
        print("a", a)

class X(A):
    ...

i = Injector(
    bindings=[ClassBinding(A, X)],
    options=InjectorOptions(auto_bindings=True)
)

b = i.inject(B)

Output:

a <__main__.A object at 0x0000020DF1469B80> # I expected an instance of X
