TokenizingTextBox Failed to Navigate between Tokens with Arrow Key Left and Right when Some Tokens Having Same Content

### Describe the bug

Like what the title said.
P.S.:Tokens not in TokenizingSample won't reproduce this bug.

### Steps to reproduce

```text
The bug can be reproduced in Windows Community Tookit Gallery.
1. Create tokens like Pic 1.
2. Press left arrow key, the highlighted token become the first, this is part of the bug.
3. Then press right arrow key twice, we'll found we can't use right arrow key to continue navigating, and we can't even navigate back by pressing left arrow key.

P.S.:Tokens not in TokenizingSample won't reproduce this bug, and up and down arrow keys are still usable.
```

### Expected behavior

The highlighted token will be the last one when pressing left arrow key when, and could navigate to all other tokens using left and right arrow key.

Inizia riproducendo il problema in Windows Community Toolkit Gallery con TokenizingTextBox e la configurazione dei token mostrata in Pic 1, quindi esamina i punti di ingresso TokenizingTextBox e TokenizingSample. Il lavoro è completato quando i tasti freccia sinistra e destra possono spostarsi tra tutti i token, inclusi i token adiacenti con contenuto identico, senza alterare l’ordine di selezione.

Scritto dal modello di indicizzazione a partire dal testo della issue.
