background插件background和backgroundImage同时设置的问题 #5915

Describe the bug / 问题描述

1：当把背景图的插件设置：background和backgroundImage同时存在时会出现问题，内部是否需要backgroundImage优先于background { type: 'background', background: 'red', backgroundImage: 'url(https://mdn.alipayobjects.com/huamei_qa8qxu/afts/img/A*0Qq0ToQm1rEAAAAAAAAAAAAADmJ7AQ/original)', backgrounfRepeat: 'no-repeat', backgroundSize: 'cover', opacity: 1, } : 2：当设置背景图的opacity为1时，网格线被覆盖，网格线层级应该高于背景图吧
