Changes for 2.1.30
- Changed the behavior of GraphLinksModel so that the use of a key of a non-existent node can be resolved by adding a node with that key in a later transaction, not just in the same transaction.
- Fixed routing of duplicate orthogonal links between ports with "...Side" Spots to avoid producing little loops when the ports are close to each other.
- Fixed ContextMenuTool to automatically stop running if the newly shown context menu is a not-GraphObject.visible Adornment.
- Fixed exception on expanding a Group whose member nodes had partly disconnected links.
