Test suite using code generator fails to compile with cabal v2-repl

[RyanGlScott]

A test suite that depends on a code generator will successfully build with cabal v2-build, but not with cabal v2-repl.

To Reproduce

1. Clone https://github.com/RyanGlScott/code-generators-issue, which contains a minimal reproducer for the bug.

2. Run cabal v2-build code-generators-issue-test and observe that it succeeds:

   $ cabal v2-build code-generators-issue-test
   Build profile: -w ghc-9.2.4 -O1
   In order, the following will be built (use -v for more details):
    - code-generators-issue-0.1 (test:code-generators-issue-test) (additional components to build)
   Preprocessing test suite 'code-generators-issue-test' for code-generators-issue-0.1..
   Building test suite 'code-generators-issue-test' for code-generators-issue-0.1..

3. Run cabal v2-repl code-generators-issue-test and observe that it fails:

   $ cabal v2-repl code-generators-issue-test
   Build profile: -w ghc-9.2.4 -O1
   In order, the following will be built (use -v for more details):
    - code-generators-issue-0.1 (test:code-generators-issue-test) (ephemeral targets)
   Preprocessing test suite 'code-generators-issue-test' for code-generators-issue-0.1..

       Use -v (or `:set -v` in ghci) to see a list of the files searched for.

   3 | import GeneratedFile
     | ^^^^^^^^^^^^^^^^^^^^
   Failed, no modules loaded.
   

Expected behavior
I would expect both to succeed.
