Steps to Reproduce

1. Run the given Sample - Issue25724.zip
2. Tap the "Toggle Header" button to hide the header.
3. Tap the "Toggle Header" button again to show the header.
4. The header does not toggle; no action occurs.

Windows Issue:

Problem: After tapping the "Toggle Header" or "Toggle Footer" buttons, the header or footer text gets removed (empties), but it does not return after toggling again. This results in the header/footer not being restored.
Expected Result:
The header/footer should toggle correctly, with the text being displayed when the header/footer is shown.
Actual Result:
After toggling, the header or footer text remains empty and does not return to its original state.

Android Issue:

Problem: On Android, tapping either the "Toggle Header" or "Toggle Footer" buttons has no effect. The header and footer are not hidden or shown when the buttons are clicked.
Expected Result:
The header/footer should toggle visibility when the corresponding button is tapped.
Actual Result:
Tapping the "Toggle Header" or "Toggle Footer" button does not trigger any changes in the UI.
