Question, if we remove an element in the array, perform the changes we need and re-add to the array, then won't the array be added at the end of the array and not at the original index as an update should be? For example: You delete the array at index 0 in an array of three elements, and then when you add it again with new data using array union, it gets added to array and now has index 2?
