Embargo plugin - Inability to 'view' embargoed content in channel view

The channel view doesn't seem to use the logged in user's permission levels to retrieve documents. Instead it seems that the 'previewuser' may be used. This means that users with permission to embargo content sometimes can't see this content using the channel view, depending on how the customer has configured their site (e.g. component/link processor behaviour).

If the channel view used the logged in user's credentials, then embargoed content should be able to be surfaced.
