When using blue ocean (I think starting from beta 11 or so), the links in GitHub status were replaced by BlueOcean links, but, at least for matrix projects, these links are broken, for example this is a matrix project that lives in a folder "thefolder" and is called "theproject" in Jenkins, the link used by blueocean is:
https://jenkins/blue/organizations/jenkins/thefolder%2Ftheproject%2FDIST%3Dtrusty/detail/trusty/921/pipeline
while the correct non-blue ocean link is:
https://jenkins/job/thefolder/job/theproject/921/DIST=trusty/

Going through the blue ocean web interface to the project, nothing is even shown.

If this can't be fixed soon, there should be at least an option to enable/disable replacing conventional links with blue ocean links, this makes using blue ocean practically impossible with github testing.
