How to Implement Snap-Enabled Dragging in a Container Using jQuery UI

Issue Description (Fiddle):

I am using the jQuery UI's .draggable() function to make the red element snap inside the blue container. However, it is snapping to one edge only instead of completely fitting inside (both edges). It requires further dragging until it snaps onto the other axis.

Is there a method to detect when the snap event initiates (the event fires) and then manually reposition the red box so that it fully fits within the container at any angle?

Sample Code:

HTML:

<div id="box"></div>
<div id="container"></div>

JavaScript:

$('#box').draggable({
    snap: '#container',
    snapMode: 'inner',
    snapTolerance: 50
});

CSS:

#box {
    background: red;
    width: 100px;
    height: 100px;
    position: absolute;
    z-index: 1;
}
#container {
    width: 102px;
    height: 102px;
    position: absolute;
    top: 50%;
    left: 50%;
    margin-top: -51px;
    margin-left: -51px;
    border: 1px solid blue;
}

If you need help with the snap event, refer to this Stack Overflow post: Jquery UI – draggable 'snap' event

Currently, after an object snaps into place, it can no longer be dragged which could pose a problem.

It's worth noting that triggering mouseup to cancel the drag event is not possible and may result in a known JavaScript error. You can see an example of this in a previous fiddle here: http://jsfiddle.net/W8yaz/7/

Here is the JavaScript code snippet:

$('#box').draggable({
    snap: '#container',
    snapMode: 'inner',
    snapTolerance: 50,
    drag: function (event, ui) {
        if ($(this).hasClass('snapped')) {
            var position = $('#container').position();

            $(this).css({
                top: position.top,
                left: position.left
            });
            return false;
        } else {
            var draggable = $(this).data("uiDraggable");
            $.each(draggable.snapElements, function (index, element) {
                if (element.snapping) {
                    draggable._trigger("snapped", event, $.extend({}, ui, {
                        snapElement: $(element.item)
                    }));
                }
            });
        }
    },
    snapped: function (event, ui) {
        $(this).addClass('snapped');
    }
});
