Now you’ve jogged my memory – this was reported back in March.
I added the emphasis on both in the quote above, because I wanted to point out that the expand and expand/shrink options only work on objects that display data, like text display objects and image display objects. They have no effect on a data tile object. It doesn’t hurt anything to make a data tile expandable, but it doesn’t help either. Expandable objects will automatically expand and shrink any objects that enclose them, including rectangles and data tiles. These enclosing object change size in response to the objects inside them. They have no data themselves, so they have no way to expand or shrink on their own.
Here’s another way to look at it. The expand and expand/shrink options tell Panorama to set the height of the object based on the data it is displaying. Data tiles, rectangles, etc. don’t display any data themselves, so the expand and expand/shrink option settings on these types of objects are ignored.
