XF 1.3 How to fix incorrect anchor positions because of sticky header?

When a site has a sticky header (like AVForums), the desired position of an anchor becomes offset by the height of the stuck header.
So scrolling to a particular post in a thread (like when a member opens a thread and it scrolls to the first new post since they last visited), actually scrolls too far down.
Illustrated here. When scrolling to post #5668, we want to see this:

How can I fix this please?
Needed 3 Hours to solve this problem :D

Add this Javascript Code in Header:

<script type='text/javascript'>

$(document).ready(function () {
$('a').on('click', function (e) {
// e.preventDefault();

var target = this.hash,
$target = $(target);

$('html, body').stop().animate({
'scrollTop': $target.offset().top-95
}, 900, 'swing', function () {


return false;

Thats all, with "top-95" you can choose the position you need.
