Visual bug: links are not following their blocks when moving root node on flat dags

[placer14]

Steps to produce:

1. Upload a file (https://user-images.githubusercontent.com/305332/60381585-735fc800-9a57-11e9-906f-29db82f57e55.jpg)
2. Change chunk size to 32 bytes
3. Change to flag dag format
4. Move the root away from it's default location and observe the links being stuck in place without following the root node representation.
