WordPress/wp-admin/includes/widgets.php
Scott Taylor 7f8b548df1 In HTML5, the action attribute is no longer required. Remove this attribute when empty.
The admin HTML is served with the HTML5 doctype.

"The action and formaction content attributes, if specified, must have a value that is a valid non-empty URL potentially surrounded by spaces."
