TextBlocks are not read by screen readers when they are used in a XAML Islands app
Describe the bug
TextBlocks are not read by Narrator and NVDA when they are used in a XAML Islands app.
Steps to reproduce the bug
Verified this behavior in the following places:
- Windows Terminal Settings UI (NavigationView scenario)
- Xaml Islands Sample App
- "Win UI Navigation" is not read in the navigation view (even if a button is placed as the content next to the text block)
- (when added) a text block above the "Hello from Xaml!" text box is not read
I have also tried adding a hyperlink to the text blocks, and the behavior slightly changed:
Additional context
Surprisingly, I've done a bit of testing with ContentDialogs too (see #2681). For NVDA, the text blocks are actually ready when the Content Dialog opens (except for the title). This further makes me think that the issue isn't that the automation properties aren't being exposed, but rather we need to notify the screen reader for when to read the text block.

Narrator NVDA Normal Reads hyperlink, but not surrounding text. Reads text block and hyperlinked portion. Xaml Islands Silence. Silence. If you enter scan mode, you are able to navigate around the text (hyperlinked and not).
Expected behavior
At a minimum, XAML Islands should have the same behavior as a non-xaml islands app.
Ideally, for hyperlinks, all screen readers would behave like NVDA. That said, that might be an issue that's on screen readers, not XAML.
The real issue here is that these text blocks are not read automatically. It seems like they're being exposed, and we're just not notifying the screen reader that we've navigated to a portion of the screen that has a text block.

I've kindly reopened a new bug to track closed issue #4399 as the team will not respond on that one.
