Yes, however these bounds are a tiny box (4px) and *not* the bounds of the actual shape (which is what is happening in for this bug report). Clicking is practically impossible if the mouseup/mousedown points have to be equivalent. Every browser that I've tested with uses Window's SM_CYDRAG/SM_CXDRAG for regular HTML elements to detect between a drag and a click. 

However, my issue is that the "click" bounds for SVG elements seem to be *the whole element* and therefore a click is always fired.
