### Reproducible in sample app?

- [ ] This bug can be reproduced in the sample app.

### Steps to reproduce

```text
1. Add RangeSelector to your page.
2. Set Minimum and Maximum properties to -100 and 100.
3. Prepare bindable properties for RangeStart and RangeEnd properties
4. Set value of bindable property for RangeStart to 0
5. The value will be overwritten to RangeSelector Minimum property value (-100)
```

まず、Minimum -100、Maximum 100、バインドされた RangeStart 値 0 で構成した RangeSelector を使って問題を再現します。RangeSelector の実装を見つけ、その範囲プロパティがバインドされた値をどのように初期化または更新するかを追跡します。バインドされた RangeStart が 0 のままになり、このシナリオを対象とする回帰テストが追加されれば完了です。
