### What happened?

The following route definition works fine as long as you don't use `url_to` or `route_to` to refer to it:

```php
$routes->get('/test(/(:any))?', 'Test::direct/$1', ['as' => 'test']);
```
Linking as below works:
```html
No parameter
1 parameter
2 parameters
```

But using both `url_to` or `route_to` fails:

```php
No parameter
1 parameter
2 parameters
```

### Steps to Reproduce

1. Add the new routes in `Routes.php`:
```php
$routes->get('/test(/(:any))?', 'Test::direct/$1', ['as' => 'test']);
$routes->get('/test_urlto(/(:any))?', 'Test::urlto/$1', ['as' => 'urlto']);
$routes->get('/test_routeto(/(:any))?', 'Test::routeto/$1', ['as' => 'routeto']);
```
2. Create the `Test` controller:
```php
$params]);
}

public function urlto(...$params): string
{
return view('test_urlto', ['params' => $params]);
}

public function routeto(...$params): string
{
return view('test_routeto', ['params' => $params]);
}
}
```

3. Create the respective views:

A) direct view

```html

Test

Testing CI4 Routing with Parameters

Test using string directly

• 
  No parameter
  


• 
  1 parameter
  


• 
  2 parameters
  


• 
  3 parameters
  

Passed Parameters

```
B) view using `url_to`

```html


Test

Testing CI4 Routing with Parameters




Test using url_to





• 
  No parameter
  


• 
  1 parameter
  


• 
  2 parameters
  


• 
  3 parameters
  



Passed Parameters









```

4. Access those views at: /test and /test_urlto

### Expected Output

No `InvalidArgumentException`, `Missing argument for "(/(:any)" in route "test_urlto(/(:any))?"` while using both `url_to` and `route_to` .

### Anything else?

- One can try it with `public bool $multipleSegmentsOneParam = true;` or `public bool $multipleSegmentsOneParam = false;` in `Routing.php`. The error is the same in both situations (just the parameters are treated differently, as expected).

- One can also use a regex like `'(/(.+))?'` instead of `(/(:any))? `. The error remains.

Reproduce the failure using the routes in Routes.php and compare url_to and route_to with both Routing.php multipleSegmentsOneParam settings. Start by tracing route parameter handling from the named regex routes; done means all shown links generate without InvalidArgumentException and preserve the expected parameters.
