Doesn't work when parent has a transformed property

[dbadrov]

E.g. when you have a markup/CSS like this:

<div className="content">
   <Sticky>
       <ul className="content-controls"> ...</ul>
   </Sticky>
</div>

Where .content has a CSS transform property (e.g. translate), the sticky doesn't work, due to the usage of position:fixed in your script, see:

and

Could you provide a jsfiddle that recreates the problem?

This is not component's issue but browsers' behavior.
Nothing to do in the component to solve it.
