FloatBorder and NormalFloat background for lsp_signature #enhancement

[alexeygumirov]

NeoVIM 0.8

I use ray-x/lsp_signature.nvim plugin for function definitions popups in the floating windows.
Additional parameters are required (as described in the relevant issue here: ray-x/lsp_signature.nvim#193), because without them floating border looks like this:

Borders for this are having default NeoVIM colors because they require following highlight to setup:

  " Neovim (LSP) diagnostics
  if has('nvim')
   ...
    exec 'hi FloatBorder' . s:bg_background
    exec 'hi NormalFloat' . s:bg_background

After this fix borders look correct:

Can you make a PR for this, please?

@NLKNguyen This seems to be a general issue: #195

I could make a PR for this specific issue (18c9cbd), but split panes are broken, too. Are you able to look into this?

Can someone check to see if this is still an issue with Neovim 0.10?
