treeGridDataSource.filter is not a function

Question

Hi, I am trying to use ejs-treegrid in my project however after dropping an element to any position I get treeGridDataSource.filter is not a function error in rowdragdrop.js at line 37. I first checked my implementation just in case I made some mistake somewhere, then I tried to use only your basic example from here https://ej2.syncfusion.com/angular/demos/#/material/grid/async-pipe and I ran into same result and error so I assume it is a problem with the library itself. The only changes I made were that I changed the component to ejs-treegrid, added [allowRowDragAndDrop]="true" and kept everything the same. I can click and drag the element as expected but cannot drop it. The problem is that in rowdragdrop.js there is this filter function treeGridDataSource.filter() but it is an object so obviously it cannot be filtered and actual items are stored in treeGridDataSource.result and this property should be filtered not the whole object. I am using syncfusion 17.4.51 and angular 8.2.14

Could you please take a look at this? Thank you ^^
