 If a setting gets set to a value in JS that is different than the
 sanitized JS-value exported from PHP, then best case there can be an extra
 refresh for a partial in the preview, and worse case (if the partial has
 to fallback to full refresh) there can be an infinite reload in the
 Customizer preview. The reason for the issue is that selective refresh is
 currently allowing partial refreshes to be triggered before the settings
 are `sync`'ed from the pane to the preview. The fix is to just prevent
 setting changes from causing a refresh until the `active` message has been
 sent from the pane to the preview.
