Affix position doesn't reset when scrolling back up

Created by: EnzoMartin

Issue occurs when using a top and bottom offset and scrolling all the way down so that the Affix gets the .affix-bottom class and a style tag with position:relative;. When you scroll back up, it doesn't remove the style tag with position:relative; which thus overrides the .affix class's position:fixed and makes it snap to the top of the page instead of affixing smoothly like when scrolling down
