Comment (by jnylen0):

 Note, [40805] is the same as [attachment:40444.3.diff] with the exception
 that `header_remove` is called directly without error suppression.  This
 is because `nocache_headers`
 [https://core.trac.wordpress.org/browser/tags/4.7.5/src/wp-
 includes/functions.php?marks=1144,1157#L1126 suppresses errors when
 calling header-related functions], but the pre-existing REST API code
 [https://core.trac.wordpress.org/browser/tags/4.7.5/src/wp-includes/rest-
 api/class-wp-rest-server.php?marks=1246#L1228 does not].
