"Marker" object flashes briefly on the screen before animating along a path

GoJS

I’m doing animation in the style of Concept Map with animation along paths

This is working pretty well for me. The only issue I have is that the Markers will briefly flash in the wrong position on the diagram before following their proper route.

Watch the attachment closely and you’ll see the markers flashing over by the node marked “Enterprise Vault”.

I’ve tried various things like setting the initial position of the node to the beginning of the path before starting the animation, and marking the node invisible until the animation loop starts, but I haven’t been able to get rid of this artifact.

The GoJS Path Animation sample does intentionally “park” tokens at nodes for a turn. Perhaps if you took that code you are still getting part of that effect?

I don’t notice that problem in the Path Animation sample – is there a way we could reproduce the problem?
