Easy and extendible tooltips for Ember

  const actualSpacing = Math.round(
    expectedGreaterDistance - expectedLesserDistance

  is the target's position. Thus, we check that the
  target's position is greater than the tooltip's
  position. */

        - Tooltip should be on the ${side} side of the target: ${isSideCorrect}.
        - On the ${side} side of the target, the tooltip should be ${spacing}px from the target but it was ${actualSpacing}px`
