Incorrect scroll to h* when sticked head used

You try calculate top offset…

var i = e("#wpadminbar");
      if (i.length > 0) {
        if (i.is(":visible")) {
          l = -30;
        } else {

…but it’s not enough for Themes with sticked head.
Please make somthing.
Thanks in advance.

p.s. IMHO There will be enough fixed bias set in the admin panel.
