The viewortStackDepth attribute is read-only at runtime; you cannot set it, and it is not used in build mode. At runtime, viewportStackDepth is automatically incremented when the actionMode attribute is set to Viewport and you zoom in on part of the data by dragging a rectangle around it. Each time you drag a rectangle, viewportStackDepth is incremented by 1.

To return to the previous viewport, use the _popPreviousViewport method.
