多页项目dev正常，build后自定义样式优先级低于框架样式

[YangJianFei]

Describe the bug

build: {
rollupOptions: {
input: {
alarm: path.resolve(__dirname, 'alarm.html'),
pass: path.resolve(__dirname, 'pass.html'),
facility: path.resolve(__dirname, 'facility-service-system.html')
}
}
},

开发模式正常，build后：

<link rel="modulepreload" href="./assets/common.edbf0978.js">
  <link rel="modulepreload" href="./assets/vendor.500d549a.js">
  <link rel="modulepreload" href="./assets/dictionary.1a017a0b.js">
  <link rel="modulepreload" href="./assets/utils.1eb921be.js">
  <link rel="stylesheet" href="./assets/common.9d3a84ec.css"> //这个自定义样式优先级降低了
  <link rel="stylesheet" href="./assets/vendor.580fc93b.css">  //框架样式优先级提高了
  <link rel="stylesheet" href="./assets/alarm.0dd66d57.css">

同样遇到类似情况，dev模式正常
prod打包后异常
ant 的 select group组件，打包后下拉option被遮挡，手动提升z-index才解决
