in this example, if you drag the node to outside diagram, and release the mouse, the diagram got error and will don’t functioning anymore.

That looks like a bug. Thanks for reporting it. We’ll fix it soon.

Thank you. This was a regression in 2.2.4, and has been fixed. The next release will be within a few days, probably.
