Nested Menu Height problem noticed in Chrome....

Using Chrome (v61.0.3163.100 (Official Build) (32-bit).

http://jqueryui.com/menu/

Notice the extra space above Electronics and Music in the menu.

If you remove: 

list-style-image: url("data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7")

from the styling of .ui-menu .ui-menu-item it gets rid of the extra space at the top.

Is that a Chrome bug?  Don't see the issue in IE 11 or Firefox 56.
