If for instance, we set a -vendor-transform: rotate(40deg) css attribute on a rectangle
This, indeed, seems to be a bug in jQuery. An easy workaround would be: surround the resizable div with a container div. Set the .draggable() to the outer div and .resizable() to the inner div. This seems to be working fine in Chromium running on Ubuntu. See Fiddle.
I've colored the outer div to give you an idea what's happening under the hood.
