bug: window.backdrop option is ignored

[hneutr]

Did you check docs and existing issues?

• I have read all the zen-mode.nvim docs
• I have searched the existing issues of zen-mode.nvim

Neovim version (nvim -v)

0.9.4

Operating system/version

MacOS 14.2.1

Describe the bug

When commit c1dea35 added default to the highlight command that sets the background color (here), it caused the window.backdrop parameter to be ignored, as zen-mode.setup is called first without a user config, which sets the default highlight, meaning that when the user calls setup, the highlight group has already been defined, and the value for window.backdrop is ignored.

Steps To Reproduce

1. :lua require("zen-mode").setup({window = {backdrop = 1}})
2. :ZenMode

Expected Behavior

the window backdrop should respect the configuration file

}
require("lazy").setup(plugins, {

})

vim.cmd.colorscheme("tokyonight")
-- add anything else here
