Cannot read properties of null (reading 'getAttribute')

Hello Syncfusion Team,

I am facing a crash where I get the following error message: 

"Cannot read properties of null (reading 'getAttribute')". It seems to occur when I am attempting to select multiple tasks using DragSelection.

If there is a way for me to disable Drag Selection so I can avoid encountering this bug (while also still having the SelectionType set to Multiple, AllowRowDragAndDrop set to true), this would be great.

In this scenario, users should still be able to use SHIFT & Click and CTRL & Click to select multiple tasks, and attempting to drag your mouse on a task should instead activate the "RowDragAndDrop" functionality.

Please refer to the video I am attaching. The video also shows the code that I used to create this bug at the 8 second mark.
