 `WP_Customize_Manager::customize_preview_settings()`.

 Thanks for the feedback, I've updated in 21627.5.diff to use the correct
 method.

 Whilst this code allows theme authors to customise the element and the
 class, it still enforces the overloaded `element.classname` selector, is
 it worth including a third setting and defaulting to the overloaded
 selector?
