Description

拖拽节点时，建议高亮更明显一点，比如inner时，dropNode整个背景高亮；before以及after时，在插入的位置添加横线高亮标识，这样用户体验应该会更好点。谢谢！

El-tree

Description
When dragging and dropping nodes, it is recommended to highlight a bit more, such as dropNode's entire background highlighted at inner, and horizontal highlights at the insertion location before and after, so the user experience should be better. Thank you!

跟这个 #12112 挺像。算是目前的 bug。

整个节点高亮，你可以通过 CSS 来控制。

.el-tree-node.is-drop-inner > .el-tree-node__content {
  background: some-color;
}

inner是可以的，但是before与after就不行，需要动源代码添加相应的class才行，我在本地动过，这个效果是可以了，只是不知道为什么，其他组件引入不进来来了
