cabal does not build documentation for repl

cabal (3.4.0) does not build documentation for ghci, even when
cabal build --enable-documentation

**To Reproduce**
cabal v2-build --enable-documentation
cabal v2-repl
Prelude Test.Util> import qualified Data.Vector as V
Prelude V Test.Util> :doc V.partition
ghc: Can't find any documentation for Data.Vector.
This is probably because the module was compiled without '-haddock',
but it's also possible that the module contains no documentation.

**Expected behavior**
obtain documentation, this used to work in previous versions?

**System information**
Build profile: -w ghc-8.8.4 -O1
linux debian
ghc, cabal from ghcup
