Switch offset when switching attachment as result of a constraint

[codepunkt]

When using a constraint, e.g. together to switch both the attachments of element and target, the defined offset is not inverted.

Example element is positioned like a dropdown, 6px below the target.

new Tether({
  element: this.el,
  attachment: 'top center',
  target: this.target,
  targetAttachment: 'bottom center',
  offset: '-6px 0',
  constraints: [{ to: 'scrollParent', attachment: 'together' }]
});

When switching both attachments, for example to attachment bottom center and targetAttachment top center due to constaint, the target is not 6px above the target - which it should be.
