Can remove the hotfix autocmd in 5e33b29 as long as the upstream issue neovim/neovim#5176 would be resolved by someone. To remove it, simply comment out the following line:

NeoTerm.lua/lua/neo-term/utils/autocmd.lua

Line 86 in 4faf099

create_hotfix_autocmds()

Note: this is pinned because it should be resolved upstream.
