Droppable tolerance "intersect" did not work properly when in exact grid

I have created a draggable object with its "grid" property having a width exactly as wide as the droppable object. The draggable object is precisely so wide that it fit over one or more droppable objects (example: three droppable objects are 50px 50px 50px 50px 50px, the draggable object is 100px, and the grid property has a width of 100).

It did not work -- ie it reported "false" -- when there were exactly two fields for it to span over. It worked with three fields. I did not try with more or less fields.

I changed

	case 'intersect':
			return (l < x1 + (draggable.helperProportions.width / 2) // Right Half
				&& x2 - (draggable.helperProportions.width / 2) < r // Left Half
				&& t < y1 + (draggable.helperProportions.height / 2) // Bottom Half
				&& y2 - (draggable.helperProportions.height / 2) < b ); // Top Half
			break;

into

	case 'intersect':
			return (l <= x1 + (draggable.helperProportions.width / 2) // Right Half
				&& x2 - (draggable.helperProportions.width / 2) < r // Left Half
				&& t < y1 + (draggable.helperProportions.height / 2) // Bottom Half
				&& y2 - (draggable.helperProportions.height / 2) < b ); // Top Half
			break;

and it worked.

Maybe you can confirm?

Perhaps the same change needs to be done with "&& t < y1 + (draggable.helperProportions.height / 2)" , if height of the draggable must match the height of one more droppables.
