Sure, no problem and nothing changes, the bug is still there.

For that GHC version you need the `bug73500.cabal` in the newly attached 
file (with dropped version constraints). It also includes the new 
`lsp-ghc92.log` transcript of `eglot` events including the diagnostics 
and `screenshot/emacs-ghc92.png` showing the fringe exclamation mark, 
but no underlining.

You must have the package `cabal-instal` providing the executable 
`cabal`. You can test that it works by running `cabal build` in the 
directory containing the cabal file.
