### Expected Behavior

Title bar, System Settings, minimize, maximize, and close control should come first in reading order when Screen Reader user navigate in scan mode by arrow key.

### Actual Behavior

Reading order of Title bar, System Settings, minimize, maximize, and close control is incorrect when Screen Reader user navigate in scan mode by arrow key as it is coming after last control. Same issue repro throughout the app.

Start by reproducing the Settings-page behavior in Windows Terminal 1.10.2383.0 with Narrator Scan mode and verify the control sequence after the Save button. Inspect the Settings UI accessibility and navigation entry points; done means the title bar, System Settings, minimize, maximize, and close controls are encountered first throughout the app, with the reported reproduction no longer occurring.
