I am using your components in my open source CMS (Using Blazor InteractiveServer) and use your Tree component quite extensively. 5.9.8 was fine, I upgraded to the latest V6 to check it out and now I can no longer collapse child tree nodes. The top level is fine, but child/nested items are not.
They open fine, but as soon as I go to collapse them the memory spikes and CPU goes up and the whole app becomes unresponsive. If I change back to v5.9.8 everything works fine again, no issues, no memory spikes or crashes no matter how deep the tree structure is.
