I somehow missed this to be a flatpak via Discover. Granted this may not be usual in distros with a traditional update model, downgrading packages may be present in rolling distros, or distros with overlapping minor versions, or having 3rd party repos providing conflicting packages to those of the distro.
I offer my system as example:
<span style="color:#323232;">The following product is going to be upgraded:
</span><span style="color:#323232;"> openSUSE Tumbleweed 20240211-0 -> 20240313-0
</span><span style="color:#323232;">
</span><span style="color:#323232;">The following 14 packages are going to be downgraded:
</span><span style="color:#323232;"> ghc-binary ghc-containers ghc-deepseq ghc-directory ghc-exceptions ghc-mtl ghc-parsec ghc-pretty ghc-process ghc-stm ghc-template-haskell ghc-text ghc-time ghc-transformers
</span>
