        <pre>Duplicate response headers should be shown individually if that is how they were sent

Test:
&lt;?php
header(&quot;X-Test-Header: Alpha&quot;, false);
header(&quot;X-Test-Header: Beta&quot;, false);
?&gt;

Steps to Reproduce:
1. Inspect test page
2. Observe Response Headers for main resource

Expected:

    X-Test-Header: Alpha
    X-Test-Header: Beta

Actual:

    X-Test-Header: Alpha, Beta

Notes:
* While technically equivalent, I'd rather see what actually instead of some reformulation:
