Bug Description

Post the latest commit supporting custom cmdline completion 7e7deaa blink will display the wrong arg when using backspace after completion.

Few examples:

fzf-lua

:FzfLua fi<tab><space><backspace>x3

nvim-cmp shows correct 2nd arg (picker name)

blink shows 3rd pos argument variables (picker options)

vim-fugitive

:Git reb<tab><space><backspace>x4

nvim-cmp shows correc 2nd arg (git operation)

blink shows 3rd pos arguments (git branch)
