• What is the current behavior?

Expected this:-

dragClass (previously dragOverClass) | string | 'drag-border' | CSS class applied on the draggable that is applied when the item is being dragged.

Applying dragClass has no effect. I have applied a dragClass but it has no effect, see example below

The dragHandle gets applied but not the dragClass

• If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem via https://plnkr.co or similar.

Create a div with draggable set. Create a CSS class for the dragClass. E.G.

 <div  [draggable]  [dragHandle]="'carousel-drag-handle'" [dragClass]="'carousel-drag'">

(related CSS file contains)
.carousel-drag {
  border:2px solid yellow;
  background-color: blue;
  max-width:20px;
  max-height:20px;
}

• What is the expected behavior?

Expected a yellow border, i.e. the CSS being applied to the element whilst it is being dragged.
