We may stop if the parentGridNode already has _cycledWithAncestorGridNode set.

> Source/WebCore/inspector/front-end/DetailedHeapshotGridNodes.js:388
> +        WebInspector.HeapSnapshotGenericObjectNode.prototype._updateHasChildren.call(this);

Please remvoe leading underscore from _updateHasChildren  method name since you override it, by the convention only private methods should start with _.

Please mention this UI change in the changelog.

We need some UI for navigating to the first occurrence of the node in the ancesors chain but this can be done in a separate patch.
