[Problem/Bug]: Narrator Find not working

What happened?

I went through the Complete guide to Narrator and in Chapter 5: Navigation, it seems that WebView2 hosted in an WPF application fails to support Narrator Find, which

Use Narrator Find to find what you need on the web, in applications, and in documents. To open Narrator Find and search for a word or phrase, press Narrator + Ctrl + F. Then, to go to the first result (starting from your cursor position), select Find next or press Enter. The narrator will focus on the result and not on the search dialog. Then press Narrator + F3 to go to the next result or Narrator + Shift + F3 to go to the previous result.

Start by reproducing the issue with a default WPF application containing WebView2, using the reported Windows, Runtime, and SDK versions. Test Narrator Find with the provided shortcut and compare the behavior with the corresponding Edge version; done means the focus behavior and reproduction status are documented.
