Description

• related issue(When I'm using with Semantic ui #979)
• additional context
  • position: fixed is based on viewport as container block but when the one of the ancestors has transform, perspective and filter, container block is changed as that ancestor block. So, the position of the layer should be calculated by using fixed grid container block with absolute position.

이 변수는 mounted라 해도 되지 않을까요? 요즘은 함수가 아닌 이상 is를 안붙이는 쪽으로 네이밍하고 있어서..
바로 위에 있는 selectFinish도 is가 없으니 일관성 차원에서도 좋을 것 같습니다.

라고 적었는데, mounted 메소드가 있어서 문제군요. 답이 없네요 -ㅁ-
