Comment (by westonruter):

 @dlh hummm, you're right:

 {{{
 > echo preg_replace( '/(attr)/', '$1 ' . preg_quote( 'data-customize-
 partial-id' ) , 'attr' );
 < attr data\-customize\-partial\-id
 }}}

 OK, it seems the answer is right in the docs for `preg_replace`:
 http://php.net/manual/en/function.preg-replace.php

 > To use backslash in replacement, it must be doubled.

 I've replaced `preg_quote()` with `str_replace()` in
 [attachment:41488.4.diff].
