I am seeing an issue with my kendo treelist control in version (2023.2.718) which is reproducible in kendo dojo (https://dojo.telerik.com/iDogeqoh). Essentially, I set my treelist to be reorderable and filterable using row filters. When I do this, I cannot type into the filter and holding and dragging the filter box seems to treat it like a header instead. In fact, when you click and drag that box, the screen freezes and you can't do anything with the page... I found that the selector being passed to the reorderable filter was '.k-grid-header th.k-header' which was being filled by the filter row. If you change this value to '.k-grid-header tr:not(.k-filter-row) th.k-header', the issue goes away.
