        border-top: 1px solid #e8eaec !important;
        padding: 10px;
    }
}
</style>

问题代码

el-dialog :model-value="props.visible" :title="props.title" :width="props.width + 'px'"
            :height="props.height + 'px'" :before-close="onClose" :close-on-click-modal="false" :append-to-body="true">
         
        </el-dialog>

解决方法

去掉 :append-to-body=“true”

修改后
