GHC Regression (GHC-87110) mixins not recognized, suggests package is hidden
## Summary
Since Version 9.12.2 (did not test 9.12.1) calling cabal repl results in the following Message when using cabal mixins:
```bash
*** Exception: <interactive>:1:1: error: [GHC-87110]
Could not load module `Relude'.
It is a member of the hidden package `relude-1.2.2.0'.
Use -v to see a list of the files searched for.
```
Hope this can be reproduced.
## Steps to reproduce
see the following files for a minimal example:
`example.cabal`:
```cabal
cabal-version: 3.4
-- This file has been generated from package.yaml by hpack version 0.38.0.
--
-- see: https://github.com/sol/hpack
name: example
version: 0.1.0.0

`app/Main.hs`
```haskell
module Main (main) where
import Example (projectName)
main :: IO ()
main = putStrLn ("Executable for " ++ projectName)
```
`src/Example.hs`:
```haskell
module Example
( projectName
) where
projectName :: String
projectName = "example"
```
## Expected behavior
I guess ghci should load without error when using mixins
## Environment
* GHC version used: 9.12.2
* Cabal version used: 3.14.1.1-p1
Optional:
* Operating System: Linux Mint 22.1
* System Architecture: x86_64 (Intel Core i9-14900HX)
