Ion-refresher shows-up before the users starts pulling

In a page without any scroll, I notice that the ion-refresher shows-up before the users starts pulling, is this a known bug or just some newbie mistake I made?

Ok, n00b mistake it is!

I was using:

<ion-refresher ... />
<div class="list card">
    <a ... />
</div>

But changing it to the following fixed the layout:

<ion-refresher ... />
<ion-list>
    <div class="card">
        <a ... />
    </div>
</ion-list>
