#33538: When customizer is loaded and after preview refresh, hidden controls in
customizer are being displayed

 Be default, there is a script forcing display of all the controls (id
 ="customize-control-{theme_options}-{setting}" class="customize-control"),
 by giving them style "display:block" when customizer panel is loaded. When
 the section is being opened, its controls become visible.

 If the logic of some controls is such that a control B should be hidden on
 the beginning depending on state of control A (e.g. A is a checkbox or
 radio showing B), there is a need to run additional custom script to hide
 the control B.

 An example:
 Control A: "Front page displays"
 Control B "Front page" and "Posts page".
 From the beginning both A and B are displayed, even if A is set to 'your
 latest posts', after change again B is shown no matter what value A has.

 After change and preview refresh, all the controls in customizer are again
 being displayed. Even those that are hidden.

 Why customizer intereferes with the logic of all the controls?
