Direction not working correctly in a grid

[B-o-s-s-e]

The direction option for swapThreshold only works on each row, but as soon as I drag the item to the next row the sorting is triggered immediately when the cursor touches the edge of an element.

issue on both directions: 'horizontal' and 'vertical'

Here is a small demo project: https://stackblitz.com/edit/angular-ngx-sortablejs-grid
