Unwanted diagram movement in GoJS Overview

I have an issue with the Overview diagram.
See the corresponding stackoverflow question here.
Thanks in advance, I hope it is sufficient to link to the question. If I should duplicate its contents and also post them here, just let me know.

This is a bug because of diagram.autoScrollRegion allowing the Diagram (Overview in this case which is a kind of Diagram) to scroll when you’re dragging the box by an edge.

This bug will be fixed in the next release (1.5.4), but you can make a workaround by setting:

myOverview.autoScrollRegion = 0;
