Bug: E315: ml_get: invalid lnum when using winbar

[lkhphuc]

Self Checks

• I'm using the latest lualine.
• I didn't find the issue in exsisting issues or prs.

How to reproduce the problem

• Install packer and lualine
• Enable winbar = {...} in setup.
• Open nvim
• Open a new buffer (:help ...) (OK)
• Enter insert mode / move cursor around
• Open a new buffer ( :help ... or floaterm ...)

Expected behaviour

No E315 error

Actual behaviour

• A page of E315: ml_get: invalid lnum
  

Minimal config to reproduce the issue

Minimal config with just packer and lualine, on neovim nightly 0.8 (the past 3-4 days all has problems).

Aditional information

If winbar is disabled in setup winbar = {}, I don't get the error even if I have configured inactive_winbar = {...} . It's only happens with winbar.

The first commit that reproduce this problem for me is #736 but I don't have this problem during testing this branch before it was merged.

Oh I just found out about this neovim/neovim#19458 , somehow google doesn't found the latest issue but only show me old one.
Closing this to track over there.

Facing the same issue :(
When using winbar I can't execute PackerSync because of this error

Did anyone find a workaround?

@augustocdias it's a bug in neovim wait for neovim/neovim#19458 to be resolved.
