<p dir="auto">Bootstrap: affix.js v3.1.1</p>
<p dir="auto">When you scroll to the bottom, the "position" system is set. But it is not "unset" when you scroll back up (unpin).</p>
<p dir="auto">I fixed the problem by changing:</p>
<p dir="auto">. if (this.unpin) this.$element.css('top', '')</p>
<p dir="auto">...to...</p>
<p dir="auto">if (this.unpin) this.$element.css('top', '').css('position', '')</p>
<p dir="auto">Dunno if this is a good "fix" or a bit of a hack.</p>
<p dir="auto">When scrolling to the bottom of the page, affix-Plugin sets the class "affix-bottom" and sets inline styles like "position: relative; top: XYZpx;". The Problem is, that the inline "position: relative" aren't removed after scrolling up again. It would be better, to set "position: relative" via the class "affix-bottom" (which works correct) and not via javascript. That would solve the problem.</p>
