<p dir="auto">When scrolling to the bottom of the page on OSX (which has the 'overscroll' effect built into browsers, I'm using Chrome but it's built into the OS from what I can see) the 'affix' sidebar behaves erratically as you overscroll.</p>
<p dir="auto">Unsure whether this was an issue in earlier releases, but it was present from at least 3RC1 onward.</p>
<p dir="auto">Poor affix is sick. Chrome for Mac. When the docs <code class="notranslate">html</code> tag is at 1201px wide, do the following:</p>
<ol dir="auto">
<li>Scroll down to the very end of the documentation's "Components" tab</li>
<li>With the Apple MightyMouse, "overscroll up" the page</li>
<li>Notice affix boy goes into oscillatory shakes mode</li>
</ol>
