Incorrect displaying nested list

Here's the issue with the content of 2 lists active/disabled of Angular,
used: macOS Ventura 13.6, chrome: Version 117.0.5938.149 (Official Build) (x86_64)

Here are steps to reproduce:
1. Open the disabled list of Angular, so it will show you a list that is related to the active list of Angular.

2. After that you need to click the active list of Angular and it shows you the arrow opened state but it is empty.

Assuming that these lists could be linked.

首先，使用附加的屏幕截图作为预期上下文，复现 issue 中描述的与启用和禁用 Angular 列表进行的两步交互。跟踪打开禁用列表、然后打开启用列表之后的嵌套列表状态；完成标准是启用列表显示其相关的嵌套条目，而不是空的展开状态。
