New node creation fails after importing diagram

[sagarwal88]

Hello.

I am new to Svelvet and was exploring some features. On this page in documentation I am importing the below JSON.

{"nodes":[{"id":"1","width":175,"height":40,"position":{"x":50,"y":50},"data":{"label":"Input Node"},"bgColor":"white","borderColor":"black","textColor":"","borderRadius":0,"image":false,"src":"","childNodes":[],"customClassName":""},{"id":"2","width":175,"height":40,"position":{"x":-193,"y":-72},"data":{"label":"Input Node"},"bgColor":"white","borderColor":"black","textColor":"","borderRadius":0,"image":false,"src":"","childNodes":[],"customClassName":""}],"edges":[{"id":"8g9wy","label":"","type":"bezier","labelBgColor":"black","labelTextColor":"black","edgeColor":"black","animate":false,"noHandle":true,"arrow":false,"source":"1","target":"2"}]}

Once imported I want to create a new node by dragging an anchor but it doesn't work. The temporary edge just hangs there and the console show this error - "Uncaught there should only be zero or one temporary edge at any given time".

This is reproducible with any flow diagram we draw, export and then import back.
