Steps to reproduce:

Dragging an element that is scaled (draggable="true" with transform: scale(0.5)). 

Attached is a file to reproduce the issue.

Actual results:

Dragged element gets unexpectedly resized and/or misplaced under the mouse pointer. 

The behavior changes depending on whether you grab the container or elements within the container.

Expected results:

The dragged element would preferably stay fixed at the position where I "grab" it and stay at the same size as it is visually presented when I begin dragging.

Not sure if relevant, but: I have tried this in a few other browsers; Google Chrome behaves strange as well. Microsoft Edge handles it perfectly, however.
