w3c css validator bug, flexbox, order property

Hi all,

The W3C Validator at:

   http://jigsaw.w3.org/css-validator/validator

by file upload

chokes on the order property of this piece of CSS:

   header {
     display: block;
     order: 1;
     flex-basis: 100%;
   }

with the following error message:

Target: file://localhost/graztimes.css

org.apache.velocity.exception.MethodInvocationException: Invocation of method 'html' in class org.apache.velocity.tools.generic.EscapeTool threw exception java.lang.NullPointerException at org/w3c/css/css/xhtml.properties[line 251, column 70]


Best regards,

Keith Andrews
