Errors when opening fugitive.vim buffers (diff, staged, specific commit versions, etc)

Information

VIM version

NVIM v0.9.5 Build type: Release

Operating System: macOS Sonoma 14.3

What went wrong

When opening a fugitive.vim buffer (simplest one is doing a git diff via :Gdiffsplit), I'm getting errors

Error detected while processing function <SNR>83_NeoVimCallback[35]..function <SNR>83_NeoVimCallback[29]..<lambda>59[1]..<SNR>77_ExitCallbac

If I set let g:ale_python_ruff_change_directory = 0 in my config, the error goes away. But I still think this is an issue that might need fixing. Pardon me if I'm wrong about that.

Reproducing the bug

1. Have nvim with fugitive and Ale configured to run linters like ruff (not sure if it's specific to ruff one, but looks like it affects all linters that do cd).
2. Create a git repo.
3. Edit an Ale-checked file in a repo.
4. Do :Gdiffsplit
5. Observe errors

I also ran into this. Does setting let g:ale_python_ruff_change_directory = 0 have any downside in general?
