Overpass turbo Can ways with Roles within relations be rendered using MapCSS

Hi Overpass turbo Can ways with Roles within relations be rendered using MapCSS

I have this routine:

https://overpass-turbo.eu/s/1ePB

rel(4137412);
way(r);
out geom;

{{style:
way[role=forward]{color:green}
}}

It contains this way with its role set as 'forward'

I was hoping it would render green. Is this possible within OPT
