Great job patching this - patching with Docker is not an easy prospect - I assume you
docker exec -it cms_web bash and then edited the file?
I’ve imported your layout into a 1.8.0-rc3 (plus patches) environment - but I don’t see any other patches that would effect the rendering in this way. Is this what you are expecting to see?
There were 2 parts to the patch mentioned in your other topic - are you sure you got them both?
