I have a strange problem today, in Chrome, when I focus on an element that is absolutely positioned out of its overflow hidden container, it gets visible in Chrome browser (
Use tabindex="-1" on your "inner-button". That will prevent focus. http://jsfiddle.net/GHgtc/2/
<input placeholder="focus on me then press tab" type="text">
<div id="container">
<a id="inner-button" tabindex="-1" href="#">You can see me !</a>
</div>
UPDATE:
I realized there is another possible solution to your issue while working on some focus issue of my own. You can use z-index:-1 if the focus you need is to be triggered later via javascript event.
#inner-button{
display: block;
background: red;
width: 20px;
height: 20px;
position: absolute;
top: 5px;
right: -20px;
z-index:-1;
}

That will keep it focusable but hidden. And you can make it visible back with z-index:0 dynamically.
