Reordering stucks in some situations

Same here! I can't upgrade to the latest version because it completely breaks the drag/collision handling on my dashboards.

Seems like I've found the piece of code that causes this issue. The bug got introduced with bug fix #43 from @mmontero that got merged a few days ago.

There must be something wrong with the calculation of the y-units (cellsToMove) in method on_stop_drag:

// get number of cells to move
var destinyRow = this.placeholder_grid_data.row + this.placeholder_grid_data.size_y;
var currentOverlappedRow = parseInt(this.gridmap[tcol][trow][0].getAttribute('data-row'));
var cellsToMove = destinyRow - currentOverlappedRow;
this.move_widget_down(this.is_widget(tcol, trow), cellsToMove);

If I replace cellsToMove with this.placeholder_grid_data.size_y everything works again as it did before the change. Unfortunately I don't really understand what is being done here so it'd be great if the user who made the original pull request could fix this.

I'm also experiencing this issue. Drag is completely unusable in my app after switching to this dsmorse fork for responsiveness. I applied the fix above, but dragging is still slow, buggy, and unusable.

Same here! In the version 0.6.9 it works properly.
