Clear and Play ignores Random button

When I tap Clear And Play, AND the Random toggle button is enabled, the same track (first in queue) always starts playing rather than a random track. It appears the Random button is ignored. My use-case is browse “high up” in my library tree to select a bunch, generally 100’s of tracks, then simply play them in random order? My 2-step workaround is tap Add To Queue then subsequently tap Play. Is this a bug?
