We using 2024.1.319.
I set up an example here: https://dojo.telerik.com/xVuefKEn. I actually want to try and prevent reordering within a multi-column columns. Normal columns I can prevent easily.
Unfortunately, it appears as though the new and old indexes are not clear. Sometimes they are the same but the column moves anyway. If I manually try to reorder it back to the oldindex, that doesn't work.
It is like the old and new indexes are incorrect in this situation.
