651f6919 - Add strictness check and made tensors into leaves if input tensors were leaves (#77474)

Add strictness check and made tensors into leaves if input tensors were leaves (#77474) I think this makes sense to do? Otherwise, if you call `backward()` in your traced function, you can't get gradients out of any tensors that should have been leaves.
