### Which server did you use?

### Database

MySQL 5.6

### What happened?

When i paginate the model like this `$UsersMode->orderBy('id_user', 'ASC')->paginate(8, 'group', $page_number);`

returns "`SELECT * FROM users ORDER BY id_user ASC LIMIT 8, 8`" based on offset and per page number

But my total count rows in the table are 24, so when i reach the end `16, 8` it returns me the same query as the last existing page in my database even with `$page_number = 100`

### Steps to Reproduce

```php
public function load_more($page_number = 2)
{
$UsersModel = new UsersModel();

$this->ViewData['Page'] = $page_number;

$this->ViewData['Users'] = $UsersMode->orderBy('id_user', 'ASC')->paginate(8, 'group', $page_number);

echo $UsersModel->db->getLastQuery();
}
```

returns "`SELECT * FROM users ORDER BY id_user ASC LIMIT 8, 8`"

But my total count rows in the table are 24, so when i reach the end `16, 8` `$page_number = 10` and go to a page number more than 3 it returns the same query "`SELECT * FROM users ORDER BY id_user ASC LIMIT 16, 8`"

### Expected Output

Going to a page number more than the total count rows of my table it should return the propper offset even if i have the total rows less than the per page number or less than the total count

`$page_number = 10` it should returns the query "`SELECT * FROM users ORDER BY id_user ASC LIMIT 80, 8`" even if i don't have enough records in my database table

### Anything else?

_No response_

Start at the Model::paginate() entry point and reproduce the behavior with the provided load_more() example, using 24 rows and page 10. Check whether the generated query preserves the requested offset; done means page 10 produces LIMIT 80, 8 even when no records exist there.
