Current behavior: When duplicating an artboard, the new artboard is created as a layer above the duplicated layer.
Desired behavior: The new artboard should be layered under the original artboard.
Reasoning: When doing an PDF export, the layer order determines the page sequence. The duplicated artboard appears to the right of the original artboard on the canvas, making it appear sequenced after the original artboard in left-to-right languages. I must always drag duplicated boards beneath their source artboard and this is repetitious.
