응또안됨
It's because iOS has some bizarre caching issue with CORS enabled images. So if you load an image with [imagePreloader.crossOrigin = "Anonymous"] and that image was already cached, then the loading will fail.
const image = new Image();
image.crossOrigin = 'Anonymous'를 지우면
이런 에러가 뜨면서 캔버스에 안올라감
Unhandled Promise Rejection: SecurityError: The operation is insecure.
아무튼 관련 정책있는데 그건 알아서들 찾아보시고
