The latest version of Diagram does not seem to provide a rotate handle on shape click. Resize handles are visible and work as before.
If I revert to an older version(2014) of dataviz the same code works normally and the rotate handle appears when you click on the shape to edit it.
I would use the old version but the old version doesn't work with some of the code I'm using for diagram.layout elements.
Is there some way to get the rotate handle working in the 2016 version of diagram?
