 > Maybe this is a newb mistake but I did some testing and couldn't get
 this to work. I applied the patch (I can see the updated source code
 applied), and modified a TwentyFourteen control (screenshot:
 http://cld.wthms.co/xG1I) with the `active_callback ` argument and no
 matter where I go on the site via the customizer I still see the control.

 Humm, works for me. Now that it has been committed to core, can you try
 again to see if your addition of the `active_callback` argument to the
 `featured_content_layout` control has the desired effect? Perhaps there
 was a problem with applying the patch.

 I tried a similar test on the latest on trunk [29057], but used an
 `active_callback`which returned a random `true`/`false` value. As
 expected, the control expanded and collapsed randomly as I navigated
 around the site in the customizer preview:
