backport 10.17

[JoviDeCroock]

Notes

Running into a lot of issues backporting #4088 because when we look up the dom in the parentInternal we basically run into the fact that we haven't reordered the parent children yet. I can make it behave a lot better by doing let nextSibling = getDomSibling({ _children: newChildren }, skewedIndex + 1); in children.js however that breaks a lot of other tests. The aforementioned issue might need a backport of the children algo split-up sooner where we first calculate the new _children array and then perform operations.
