Failure to apply inverse patchset

[michaelhabibi]

I've run into a case where apply fails when applying the inverse patchset generated by create. Take the following code example

const parentId = "parent";
const childId = "child";

const myObj = {
  [parentId]: { name: "parent", children: [childId] },
  [childId]: { name: "child" },
};

const [newState, patchset, inverse] = create(
  myObj,
  (draft) => {
    // delete children
    while (draft[parentId].children.length) {
      const id = draft[parentId].children[0];
      draft[parentId].children.splice(0, 1);
      delete draft[id]; // delete child object
    }

    // delete parent
    delete draft[parentId];
  },
  { enablePatches: { arrayLengthAssignment: false } }
);

const reverted = apply(newState, inverse); // throws an error

When trying to apply inverse to newState, apply throws the following error:

Cannot apply patch at 'parent/children/0'

Expected
The inverse patchset is correctly generated and applied.

Note
Reversing the inverse patchset in this case correctly applies it.
