$.fn.removeData can't delete data

Description

$('body').data('a',1);

$('body').removeData();

alert($('body').data('a')) still 1

alert($.expando in document.body) still true

Is it bug or my mistake? and jQuery.support.deleteExpando does not exist in 1.4.3

Bug confirmed. removeData() fails in 1.4.3 (removeData(name) still works).

It looks like the jQuery.support.deleteExpando property (and the according test in support.js) got removed by accident.

Commit where the deleteExpando property was introduced #9195107 (improvement on the previous commit #a6f3375)

We removed deleteExpando after 1.4.2, for some reason. This caused problems with removeData() (no arguments). Fixes #7209.
