Fixed "selected" not disappearing when clicking another segment on CurrentSegmentInfobox + added a selected state to AnnotationsController buttons to reflect AnnotationsList/CreateAnnotation shown/hidden state

// Resize anything

.resizable(@direction) {
  resize: @direction; // Options: horizontal, vertical, both
  overflow: auto; // Per CSS3 UI, `resize` only applies when `overflow` isn't `visible`
}
