Debug assets ignores media type for stylesheets

[moser]

When asset debugging is activated, every stylesheet link tag has media="screen".
The following code in my layout

= stylesheet_link_tag 'application', :media => "all"
= stylesheet_link_tag 'print/print', :media => "print"

produces

<link href="/assets/app.css?body=1" media="screen" rel="stylesheet" type="text/css" /> 
<link href="/assets/jquery-ui-1.8.5.custom.css?body=1" media="screen" rel="stylesheet" type="text/css" /> 
<link href="/assets/application.css?body=1" media="screen" rel="stylesheet" type="text/css" /> 
<link href="/assets/print/print.css?body=1" media="screen" rel="stylesheet" type="text/css" /> 

when the debug_assets=1 parameter is passed.
Without the parameter it works as expected:

<link href="/assets/application.css" media="all" rel="stylesheet" type="text/css" /> 
<link href="/assets/print/print.css" media="print" rel="stylesheet" type="text/css" />
