test drag position is correct within an absolute position element

[dotnetCarpenter]

Dragging within an element with position: absolute doesn't appear to work. This unit test highlight the issue. I'll work correcting this in another PR or an amendment to this.

This is interesting... I haven't thought about this before. Is it something blocking you from moving on with a project of yours?

[dotnetCarpenter]

No. Just something I think draggable.js should support. I got it semi working with translate(), but that means dropping support for some old browsers, including IE8 and less. What do you think?

[gtramontina]

I think using translate is the way to go... I'd rather support the new web than the old web (IE) :-)

Today I faced this problem,I think imporve 'getInitialPosition' function to make cross browser support would be greate,for now It just work fine with 'static' and 'fixed' position element.
