Synchronization of Node Collapse/Expand in two diagrams

GoJS

Hi @walter,

Coming back to sync problem of two diagrams (the way done in this sample: Basic Day/Hour Infinite Timeline) :

“myColumnHeaders” diagram goes out of sync with “myDiagram” when the number of rows goes out of the view.

When all the rows are in view, sync is fine:

When all the rows are in “NOT” view, diagrams goes OUT of sync:

Could you please suggest, what is the issue here, and, how can these diagrams remain sync, even when all the rows are not in view.

Thanks.
