 r43138 introduced a regression where `build/wp-
 include/js/underscore.min.js` has an invalid `sourceMapURL` value:

 {{{
 //# sourceMappingURL=underscore-min.map
 }}}

 This results in a warning in the browser console:

 {{{
 Source map error: request failed with status 404
 Resource URL: http://wp-develop.test/wp-
 includes/js/underscore.min.js?ver=1.8.3
 }}}
