Windline floating window stops updating when setting interval to zero

[JuniorSuperTux]

Windline stops updating when using the following config:

require('wlfloatline').setup({
    interval = 0
})

However, it still updates when entering command mode (with a small delay).

Everything works after changing the interval to 1, but the command mode delay still exists. It does not delay when floating window is not enabled.

Also, sometimes when I enter Neovim, this error shows:

E5108: Error executing lua [string "v:lua"]:1: attempt to call field 'floatline_show' (a nil value)

better use interval >200. interval is millisecond second and 0 mean no update.

What about the entering command disables floating window issue? Also that error message

[windwp]

enter command disable floating window because some command will print output and floating window will hide it.
i don't have that issue so you need provide how to reproduce it.
