Resizable Bug: Custom handlers did not work as jquery objects (outside the resizable element). 

I needed to use as handle a div outside the resizable element. So I tried to specify the jquery element as the documentation said but it did not work.
handles: { "s": $("#customResizableHandle") },

The documentation said in handles option:
Object:
The following keys are supported: { n, e, s, w, ne, se, sw, nw }. The value of any specified should be a jQuery selector matching the child element of the resizable to use as that handle. If the handle is not a child of the resizable, you can pass in the DOMElement or a valid jQuery object directly.

Note: When generating your own handles, each handle must have the ui-resizable-handle class, as well as the appropriate ui-resizable-{direction} class, .e.g., ui-resizable-s.

This pull fix that bug. Now I can use a handle outside the element resizable. I hope this help.

I started using a code of a Stackoverflow reply from ylebre http://stackoverflow.com/questions/958419/custom-resizable-handles-in-jquery-ui but it didn't work at the beginning so I had to change it. 

I did not create any ticket, I had to fix it at the moment,
