[BUG] MaskedBehaviour does not draw trailing format characters

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Did you read the "Reporting a bug" section on Contributing file?

- [x] I have read the "Reporting a bug" section on Contributing file: https://github.com/CommunityToolkit/Maui/blob/main/CONTRIBUTING.md#reporting-a-bug

### Current Behavior

MaskedBehavior removes all masked characters that exceed the length of the masked input string.
This means the mask `E 000° 00' 00"` with unmasked character `0` and the value `180 00 00` will be rendered as `E 180° 00' 00` without the last quote character.

### Expected Behavior

The trailing format characters should be drawn in the entry.

### Steps To Reproduce

1. Open and run solution from linked reproducible repository.
2. Enter 1200000 without spaces

Further: try adding the last quote character after 1200000

### Environment

```markdown
- .NET MAUI CommunityToolkit: 11.0.0
- OS: Microsoft Windows 10 Home (10.0.19045 Build 19045)
- .NET MAUI: 9.0.30
```

### Anything else?

Without having done any debugging I feel like the condition on [line 180 in MaskedBehavior.shared.cs](https://github.com/CommunityToolkit/Maui/blob/fbfd456d4ce00bba77a7ec47539dfa39fb6dc682/src/CommunityToolkit.Maui/Behaviors/MaskedBehavior.shared.cs#L180) is suspicious.
My understanding from reading the code is that the formatting will be applied until maximum text length is reached.
