RangeSelector: Making the maximum and minimum values the same crashes the system

### Describe the bug

The system crashes when the maximum and minimum values are set to the same value

In some cases, Ctrl+Alt+Del may be delayed before the security options appear

### Steps to reproduce

```text
1. Go to the RangeSelector page
2. Make the maximum and minimum values the same via slider (like max=0, min=0)

It may take 0-5 seconds for the system to crash
```

### Expected behavior

The app handles it correctly and does not crash

Inizia dalla pagina RangeSelector nell'app WinAppSDK / WinUI 3 e riproduci il crash impostando il minimo e il massimo dello slider sullo stesso valore, ad esempio 0. Analizza il comportamento di RangeSelector con limiti uguali e verifica che l'app rimanga reattiva e non vada in crash, anche nella configurazione Windows 11 ARM64 segnalata.
