 This is almost a bug, as most developers expect it to be present. The
 reason we haven't done it yet is that there is no JS API for sections or
 panels (which were based on sections). Now that #28709 is happening
 (probably in 4.1), we can complete the contextual Customizer objects API
 by adding support for `active_callback` to panels and sections.

 I have a starter patch for the PHP side of the API, essentially porting
 the relevant sections from `WP_Customize_Control` to `WP_Customize_Panel`
 and `WP_Customize_Section`. Once #28709 happens, we can add the JS side in
 here as well. API-wise, contextual sections and panels should work
 identically to contextual controls, with the three means of adding them
 (note that custom panels and custom sections work, just like custom
 controls).

 See #27993.
