RadzenTree node expansion triangles bug

I'm observing what appears to be a bug with RazdenTree. When I load a tree using an externally specified object, and then re-load it using a different but similar object, previously opened nodes still have the triangle "open", although unexpanded. It has to be "closed" and then re-opened, where proper expansion occurs. I am specifying that they be initially closed. This appears to be a bug.

Hi @newintellectual,

I am not sure how to reproduce that problem. Could you provide some sample code that we can try?
