Is it intentional that default routing profile at brouter.m11n.de gives illegal instructions? (ignores bicycle=use_sidepath)

See https://brouter.m11n.de/#map=17/50....nlats=20.008485,50.093715;19.994473,50.087726

But you cannot cycle there, as https://www.openstreetmap.org/way/215887783 indicates (bicycle=use_sidepath)

(sorry for English, but following instructions at the website this seemed only viable place to report problems)
