This is happening because I'm trying to set vim.opt_local.winbar on BufWinEnter, and I guess it's trying to do so on the signature float.

This is not an issue for this project. Thank you!

FYI, the 'filetype' of the signature floating window will be empty (unset), and the bufnr will be stored in global _LSP_SIG_CFG.bufnr. You can update your autocmd hook functions by filtering those out.

Awesome! Thanks for the info!
