It appears that the regex filter introduced in
JENKINS-34373 does not filter on folders
We wish a dashboard only showing the cons/ jobs
A regular expression of ".*master.*" works fine for just showing all master builds.
However a "cons/.*" a "^cons/(." or a "^cons\/(.)$" filter as suggested in
JENKINS-27270 (for a different plugin) does not work (only results in an empty board)
