Second Autoprefixer control comment was ignored. Autoprefixer applies control comment to whole block

1.多行文本省略号样式失效丢失，

/*! autoprefixer: off */

-webkit-box-orient: vertical;

/* autoprefixer: on */

2.autoprefixer警告'Autoprefixer applies control comment to whole block, not to next rules.'

/*! autoprefixer: ignore next */

-webkit-box-orient: vertical;

/* autoprefixer: on */
