你担心的下一个面板会拦住 SFB，因此设置了固定值 2016，但是我认为固定的还是不太好：

因为你不能保证用户不会用到大于 2016 的 renderOrder，因此：

1. 如果用户面板的 RenderOrder = 2017 ，那么 SFB 就显示在此面板之下，但动态RenderOrder 能够解决这个问题。
2. 你提到下一个面板会覆盖的困惑，但如果用户下一个面板 renderoder =2017 ，SFB 同样会被覆盖在新的面板下。
3. 所以，为了下一个面板大几率能够正常展示，让我们取个折中措施：把 +1 变成 +2016

以下为 gpt 翻译/ translate by gpt below：

You are concerned that the next panel will block SFB, so you set a fixed value of 2016, but I think it is still not ideal:

Because you cannot guarantee that users will not use a renderOrder greater than 2016, so:

1. If the user's panel has a RenderOrder = 2017, then SFB will be displayed below this panel, but dynamic RenderOrder can solve this problem.
2. You mentioned confusion about the next panel covering, what if the user's next panel render order = 2017, SFB will also be covered under the new panel.
3. Therefore, in order for the next panel to have a higher chance of displaying correctly, let's compromise: change +1 to +2016
