Lines not duplicated with Grid Layout Rectangle Container. Is this expected behaviour?
I have a LucidChart document, that uses Grid LayOut Rectangle Container with a standard Block in it. This Block in the container has a line towards another Block, outside the container. So the lines goes across the container-boundary:

When I duplicate this Page, the duplicate page contains the Container and the boxes, but the line is missing:

Is this expected behaviour?
For me as a user, this is counter-intuitive, and I would expect a full duplicate, including all lines.
