Hi,

Currently, when following the documentation for Targeting content to a channel I can target some content to a channel, for instance it seems to work fine for content in the main area. However, if I try to do the same for content in the extras area, base area, or footer area, the content that should not be rendered for a particular channel is still rendered. I've been able to reproduce the issue on demoauthor site.

Steps to Reproduce:

1. Add tabChannels to dialogs/pages/footer/stkFooterLinkInternal
2. On the demo-project home page, edit the Contact Us link in the footer to open the dialog
3. In the Edit dialog, click on the Channels tab check the Desktop checkbox to exclude the content from the Desktop channel, then click the Save button
4. Select the Preview button, and choose Desktop from the dropdown menu
5. Note that the Contact Us link in the footer is still rendered for the Desktop channel.

Let me know if you have any questions.

Cheers,
Matt
