Static filters still ignore orphaned content

How to reproduce it : 

• Create this filter

• <filter id="alerte" target="content"> 
   <context type="current-site"/>
   <content-types> 
   <type id="content-type.alertes"/> 
   </content-types> 
   <view>abstract</view> 
   <metadata condition="AND">
   <metadata id="start-date" type="date" operator="lte">today</metadata>
   <metadata id="end-date" type="date" operator="gte">today</metadata>
   </metadata> 
   <sort-information>
  <sort metadataId="publication-date" ascending="true"/> 
   </sort-information> 
   <mask-orphan>false</mask-orphan>
   </filter>

• And orphan doesn't appear in the cocoon view content
