Links to Nodelet helppages disabled

I noticed that all nodelets have help-pages (like this) which are linked to via <sup>?</sup> next to the name

But the display is disabled via CSS

<a class="nodelethead-annot" href="?node=About the XP Nodelet">
<sup>?</sup>
</a>
[download]

a.nodelethead-annot {
    display: none;
}
[download]

Why?
