Increase 1 million list item limit for Order list action

[KatherineY]

Requesting to increase the limit of 1 million list item count for Order list action.

Currently we will get the following error when list item is over 1 million:

Cannot Run Action

The number of items in the list (1000001) exceeds the maximum allowed (1000000)

The issue with the current limit is that it seems to be applied to the total number of items in the list rather than the number of children a parent has. Since the sort is done within the confines of the parent it would seem that the limit should be on the maximum number of children any immediate parent has perhaps? but failing that then I would support the increase of the limit to a larger number.
