Problem:
When a container element wrapping the SortableJS interaction is being scaled with a CSS transform and forceFallback: true is being used, there appears to be an error in the calculation of scaling for the .sortable-fallback element, causing it to continually rescale ever smaller/larger on each drag position update.
With a scale of less than 1 on the ancestor element, the dragged item vanishes to oblivion and over-corrects X/Y position. With a scale of greater than 1, the dragged item grows to encompass the whole screen.
It seems that a calculation that should be happening once to correct for the scale is instead happening continuously and cumulatively.
This behaviour does not appear to exist in 1.9.0.
