[Problem/Bug]: Narrator Left Arrow jumps to end of WebView2 content instead of previous elemen #5470
Description
What happened?
When using Narrator in WebView2 content on Windows ARM64, pressing Left Arrow while focused on the first element causes Narrator to incorrectly jump to the last element in the document, instead of staying on the first element or doing nothing. This creates unexpected circular navigation behavior.
Importance
Moderate. My app's user experience is affected, but still usable.
Runtime Channel

Runtime Version
143.0.3650.80 (arm64)
SDK Version

OS Version

Repro steps
When a Narrator user navigates into WebView2 content:
- User presses Tab to enter WebView2 → Focus lands on first element
- User navigates forward with Right Arrow → Moves to next elements
- User navigates back with Left Arrow → Works correctly for middle/end elements
- BUG: When user is on the FIRST element and presses Left Arrow, Narrator jumps to the LAST element.
This creates unexpected "wrap-around" navigation that disorients screen reader users.
Expected Behavior
When user presses Left Arrow while on the first element in WebView2:
Option 1 (Preferred):
- Narrator should stay on the first element (no navigation)
- Similar to how reaching the end works in most documents
Option 2 (Acceptable):
- Narrator could play a boundary sound/announcement
- But should NOT jump to last element
