color of steps not displayed proper with josm internal and additional mapcss style

[Klumbumbus]

the attached .osm file contains 4 ways, wich are highway=service, residential, steps and primary. If you use the JOSM internal mappaint style and the attached .mapcss file (which contais just the following code)

way[highway] {width: 6; color: red;}

the steps are displayed in another color. See Screenshot.

What is the expected result?
The .mapcss file should override the color of the internal style and display steps like the other highways in the example.
