Clicking on a section in the Administration menu doesn't work

Clicking on "Users and Groups", "Global Settings" etc doesn't work. This is because function cookieShow in atlassian-jira/includes/js/cookieUtil.js only takes one parameter:

function cookieShow(id)

while the invocation emitted by atlassian-jira/decorators/panels/adminpanel.jsp is written

var id = "admin-<%= menuName %>";
cookieShow(id, '');

Removing the second parameter from the latter fixes this issue.
