Reordering to the selected row crashes

Forum post

Hi,
We have found an issue reordering rows in one of the available Bryntum's grid examples.
Selecting multiple rows and dragging them to do a reorder operation sometimes the grid breaks, making impossible to continue doing any other operation in the grid. Also, we have observed that reordering multiple rows after dropping the rows, not all rows are always kept as selected.
See gif attached.

Could you please take a look?
Thanks
