VoiceOver focus order breaks when UI is updated asynchronously

Description

When UI is updated from some asynchronous call like setTimeout, it seems the focus order of elements on the screens becomes broken (even when that focus order is correct before the UI change). The focus order jumps outside of the app (into the OS status bar, it seems?) and becomes trapped.

This seems like it may be related to https://github.com/react/react-native/issues/49462, but there are a few important differences I want to focus on:

1. No keyboard behavior at all.
2. This is not a problem that needs to be solved with custom focus order: the focus order is originally correct in a simple screen, but breaks when UI is changed from a setTimeout (I'm assuming it has something to do with being an async UI update, but I haven't discovered enough details yet to back up that claim)

Steps to reproduce

1. Install the reproducer on an iPhone device
2. Open the application
3. Turn on VoiceOver
4. Walk through the screen. The focus order should work as you'd expect (goes down the screen in-order as elements are written)
5. Move the focus back up to the "A" button and double tap to use it. UI is updated
6. Move focus down the screen to the "B" button. It should work as it did in your first pass.
7. Double tap the "B" button, wait for text to update to "2 new messages"
8. Swipe to move focus down. Now you'll notice a few issues:

First issue: we read out the stale "checking for new messages" text, which is no longer visible if you waited for the messages to be checked and resolve to "2 new messages"

Second issue: if you try to move focus past "2 new messages" by swiping right, your focus jumps up to the top of the screen, and then you can't get out of it by swiping left or right.

首先在启用 VoiceOver 的 iPhone 上安装并运行 https://github.com/coolsoftwaretyler/focusissues 中的强制复现程序，然后按照列出的步骤操作，以观察异步更新后出现的过时文本和被困住的焦点。更新后的文本能够被朗读，并且向右滑过该文本时仍保持预期的焦点顺序而不会跳出应用，即表示完成。
