Setup
On macOS, Skim is configured with nvim --headless -c "VimtexInverseSearch %l '%f'" as recommended.
In Space foo, I have a Ghostty window running Neovim on the file foo.tex and a Skim window showing me the resulting pdf.
Inverse search works great ✓
In Space bar, I have a duplicated setup but on a different file bar.tex.
Inverse search works great too ✓
Incident
Quit Neovim foo → Inverse search stops working for bar ✗
Reopen nvim foo.tex → Inverse search starts working again for bar ‽
