TextBox in ListView hidden behind On-Screen Keyboard

Nobody has claimed this yet.

### Describe the bug

When using a ListView with TextBox items and enabling the On-Screen Keyboard (OSK) setting, focusing on an Entry causes the keyboard to appear, but the focused Entry is hidden behind it. The ListView does not scroll automatically to keep the focused element in view.

### Steps to reproduce the bug

1.Enable OSK setting in Windows.
Enable the touch screen via Windows Settings -> Personalization -> Text Input -> Touch Keyboard and Windows Settings -> Time & Language -> Typing -> Touch Keyboard to always.
2.Use a ListView with Entry/TextBox template.
3.Focus on a lower Entry item — it gets covered by the keyboard.

### Expected behavior

The ListView should automatically scroll to ensure the focused Entry is visible above the keyboard.

Actual Behavior:
Focused Entry gets hidden behind the On-Screen Keyboard and is not accessible without manually scrolling.
