*regression* Popover arrow is not repositioned if popover is repositioned
Created by: childnode
while tooltip uses .arrow() getting the right arrow node addressing this by using the class name "tooltip-arrow" as defined in the tooltip template, it is not overwritten in popover so inheritance causes popover is looking for tooltip-arrow while running though .replaceArrow() but popover has another template with class 'arrow' instead of 'tooltip-arrow'
