Newline in title element causes "Too many nested function calls" error

```html
<html>
    <head>
        
        <title>Test test</title>

        
        <title>Test
               test</title>
    </head>
    <body>…</body>
</html>
```

We can fix this during preprocessing but it seems like a bug that should be fixed in dotify (presumably) at some point.
