F41 Beta dnf: "update" updates 100+ but "distro-sync" downgrades?

Er, it looks like update updates stuff, distro-sync downgrades and puts F41 back to Prerelease, and distro-sync immediately after that wants to update stuff again?

  • F41 beta install
  • distro-sync
  • Prerelease → not Prerelease
  • update
  • (nothing to install)
  • distro-sync
  • not Prerelease → back to Prerelease
  • distro-sync
  • Prerelease → not Prerelease

It seems like distro-sync can loop between updating and downgrading packages and seems to remove the Test Updates repo when it “updates” the OS to not-Prerelease.

I’m still not quite sure what’s going on, but it seems like update works consistently.
