Draggable: _adjustOffsetFromHelper not reinvoked after "start" event is fired

[marcel.jackwerth]

While _cacheHelperProportions is reinvoked after the start-event, _adjustOffsetFromHelper is not. This leads to issues if you use right/bottom offsets (which depend on width/height) and you modify the helper (or it's content) during the start-event.

Here's the code of draggables mouseStart (removed irrelevant code for this problem)

//Cache the helper size
this._cacheHelperProportions();

//Adjust the mouse offset relative to the helper if 'cursorAt' is supplied
(o.cursorAt && this._adjustOffsetFromHelper(o.cursorAt));

//Recache the helper size
this._cacheHelperProportions();

This could be fixed if we just add another _adjustOffsetFromHelper after the re-caching or are there any side-effects I am missing?

this._cacheHelperProportions();
(o.cursorAt && this._adjustOffsetFromHelper(o.cursorAt));

This makes sense. The offset should be adjusted after the start event is fired.
