winfixbuf leads to duplicate status window after interactive rebase

[tom-anders]

Precondition: (n)vim supports winfixbuf

Reproduction steps:

• :G status (with unpushed changes)
• Put cursor over a commit and press rw (interactive rebase with reword)
• In rebase edit window, press :wq
• in commit message window, press :wq -> You now have two status windows

Testing in Neovim, I can't reproduce. You could try reverting each of 8d4e8d45385c63a0bf735fe1164772116bf0da0d and 8d4e8d45385c63a0bf735fe1164772116bf0da0d to see which one is responsible. And make sure to try with other plugins disabled.

Okay I bisected by config and nailed it down to Konfekt/FastFold.

Not sure which plugin causes the actual issue, but I'm commenting here just for future reference if other people encounter this problem.

Here's a minimal init.lua that reproduces the issue:

local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({
    "git",
    "clone",
    "--filter=blob:none",
    "https://github.com/folke/lazy.nvim.git",
    "--branch=stable", -- latest stable release
    lazypath,
  })
end
vim.opt.rtp:prepend(lazypath)

require'lazy'.setup {
    {'tpope/vim-fugitive'},
    {'Konfekt/FastFold'},
}
