For example I took an DockingIntegration_WPF project from examples provided by Telerik. I set up grid snapping and it has worked fine, until I have rotated the shape on 90 (or 270) degrees.
After rotation, the shape does not snap to grid neither when I drag it over the diagram nor I drop it on the diagram.
But when I rotate the shape on 180 degrees , it snaps to grid well.
On attached picture you can see this bug.
Is it possible to fix this issue?
