Hi,

I got a blade file as follows:
```php
@if((new \Jenssegers\Agent\Agent())->isDesktop())
@extends('layouts.app')

@section('content')

DESKTOP VERSION

@endsection
@endif
@if((new \Jenssegers\Agent\Agent())->isMobile())

MOBILE VERSION

@endif
```

The h1 tags are working as expected, on desktop it shows `DESKTOP VERSION` and on mobile it shows `MOBILE VERSION`.

But the same layout `layouts.app` is being rendered on both clients.

I expected the layout to be used only by the desktop, but it's being rendered on mobile too.

Reproduce the behavior using the supplied Blade view and the layouts.app view with desktop and mobile requests. Inspect how the conditional Blade content and layout extension are processed, then confirm whether the layout is rendered only for desktop or document the required change.

Written by the indexing model from the issue text.
