Subject: [PATCH] Prevent accidental body class concatenation by replacing
 (no-)customize-support with a space

The regular expression used by wp_customize_support_script() replaces all spaces
surrounding the matching class. This caused other classes to be merged together.

Props johnpbloch, SergeyBiryukov. Fixes #22103.
