Unfortunately, it was never intended to allow duplicate values, as this component makes an assumption that each node has a different value. While allowing duplicate values could be seen as a feature in some use cases and contexts, in most scenarios it should be considered an issue.

I suppose the component could have another property, say allowDuplicateValues, that would allow the behavior you relied upon in the older version, but admittedly that is not high priority right now.

Hello,
I would like to +1 this one and challenge the fact that it is considered an enhancement.
Actually being a change released in the same major, this one should be considered a regression as it contains non backward compatible changes.
