Blade not supporting nested yields

I have a sample view:

File: hello.blade.php

//includes the basic html enclosed tags
<p>Hello world<p>
@yield('content')

File: tester.blade.php

@extends('hello')
@section('content')
  <p>this is a test<p>
  @yield('contents') 
@endsection

File: content.blade.php

@extends('tester.blade.php')
@section('contents')
  <p>any code will do<p>
@endsection

now my problem is whenever it only renders

Hello world
this is a test

is there any workaround this? or blade engine does not support nested yields? anyhelp will be greatly appreciated
