### Expected Behavior

Screen reader should narrate as 'blank' for the empty lines, while navigating in the editor via 'Ctrl+Arrow keys'.

Note:
1.Screen reader is not narrating as 'Blank' for the empty 'Name' field present for the 'Default' settings.

### Actual Behavior

Screen reader is staying silent & not narrating anything for the empty line, while navigating in the editor via 'Ctrl+Arrow keys'.

The issue names no source file, test, or entry point. Start by reproducing the behavior in Windows Terminal with Windows PowerShell, Narrator, scan mode, and Ctrl+Arrow keys, using the attached recording as reference. Done means Narrator announces “blank” for empty editor lines and the empty Default settings Name field.
