inconsistent result from $.data

[anonymous]

Please see the example here: ​http://jsfiddle.net/k8hBY/4/

If there is a data attribute with a number in the name like (data-test-1 or data-test-1-test) that attribute value will not be returned by $(el).data()

However if you call $(el).data('test-1') before calling $(el).data() the result is correct.

Use the W3C-standard camelCase naming if you want to retrieve directly from the object returned from .data(). ​http://api.jquery.com/data/#data-html5
