How to reproduce the issue

nvim --clean

1. :lua =vim.api.nvim_get_hl_by_name("Normal", true) prints:

{                                                                                                             
  [true] = 6
}

2. Set highlight via lua vim.api.nvim_set_hl(0, "Normal", { fg = "#ff0000", bg = "#202020" }). 1) prints:

{                                                                                                             
  [true] = 6
}

3. Set highlight via :hi Normal guifg=#ff0000 guibg=#202020. 1) prints:

{
  background = 2105376,
  foreground = 16711680
}

Note: This behavior might be specific to the Normal group.

Expected behavior

nvim_get_hl_by_name("Normal", true) returns the group's colors.

Actual behavior

It only does so when the highlights are set the vimscript way.
