Can't configure syntax highlighting in code macro

According to this (http://extensions.xwiki.org/xwiki/bin/view/Extension/Code%20Macro) it should be possible to change the syntax highlighting theme for the code macro, but I have inserted the line "rendering.macro.code.pygments.style="vs"" into my xwiki.properties and rebooted the server with no change at all. This issue (https://jira.xwiki.org/browse/XWIKI-5167) says it's been fixed, am I just missing something?
