On Snap method doesn't triggered with existing blocks

[vladkash]

Hello, thank you for the library, I have an issue.

"onSnap" method has triggered when I add a new block to a flowchart, so I can resolve the result of attaching. But when I attach an existing block on the chart to another it hasn't triggered so my rules of attaching don't work.

Hmm you mean when rearranging the blocks? I could add this feature - what would happen if you wanted to prevent the attachment when rearranging? Should it revert to the previous parent, similar to the onRearrange method?

Yes, it should
