Expand/Collapse removes class from node in TreeList
Hi, I found a bug which is reproduced in following dojo: https://dojo.telerik.com/OcaTEbOk
I need to disable row which meet some conditions after dataBound event. To do that class 'k-disabled' is added to each tr in grid and it works fine. Now, I collapse node with disabled rows and expand it again. Even nodes are indeed disabled but odd nodes are enabled (k-disabled class is removed from these rows). Check example provided above. Try to collapse 'Constance Vazquez' node (there are only disabled rows there) and expand again.

This behavior was originally reported several years ago and has not received significant demand or follow-up from the community since then. This is why we plan to prioritize more impactful and widely requested improvements. 

If this limitation is still affecting your scenario, please share additional context or use cases. This will help us better assess severity and reconsider prioritization in the future. Thank you!
