Describe the bug

Hello,

I am in the weeds of configuring my neovim and I'm confused with a few things. I wasn't sure where to post this, as it relates to multiple plugins, and default neovim, so I thought it would be prudent to post here.

I know this is quite contrived, but this wide array of issues probably points to my configuration having underlying base issues, I hope someone can help me understand better how to correctly fix this. Thank you in advance.

Expected behaviour

• The trouble menu should have highlighting for the current line (currently the background is the same color).
• Mini.icons should be set up correctly (I'm not sure if I should manually override or if this should automatically happen with mini.icons installation)
• What's weird is that lualine icons seem to work correctly out of the box without overriding.
• The icon selection should be consistent (everything should use mini.icons)

My config (lazy.nvim)

{
	"ellisonleao/gruvbox.nvim",
	priority = 1000,
	config = function()
		require("gruvbox").setup()
		vim.cmd([[colorscheme gruvbox]])
	end,
},
{
	"echasnovski/mini.icons",
	lazy = false,
	config = function()
		require("mini.icons").setup()
		MiniIcons.mock_nvim_web_devicons()
	end,
},
{
	"nvim-lualine/lualine.nvim",
	dependencies = { "echasnovski/mini.icons" },
	config = function()
		require("lualine").setup({
			options = {
				theme = "gruvbox",
				icons_enabled = true,
			},
			sections = {
				lualine_a = {
					{
						"mode",
						fmt = function(str)
							return str:sub(1, 1)
						end,
					},
				},
				lualine_b = {
					{
						"branch",
						fmt = function(str)
							return str:sub(1, 7)
						end,
					},
					"diff",
					"diagnostics",
				},
				lualine_c = { "filename" },
				lualine_x = { "filetype" },
				lualine_y = { "progress" },
				lualine_z = { "location" },
			},
			inactive_sections = {
				lualine_c = { "filename" },
				lualine_x = { "location" },
			},
			tabline = {
				lualine_a = {
					{
						"buffers",
						show_filename_only = true, -- Shows shortened relative path when set to false.
						show_modified_status = true, -- Shows indicator when the buffer is modified.
					},
				},
			},
		})
	end,
},

Screenshots

1. As you can see, in my trouble.nvim bottom buffer I don't have any highlighting happening over line 39, even though I'm hovered over it. I verified that this works with the default theme.
2. Another issue is on the left WARN and ERROR diagnostic there's a contrast between the icon background and the regular vertical bar background.
3. I wasn't sure how to correctly set up the vim.diagnostic icons correctly with mini.icons.
4. I'm also using tiny-inline-diagnostic.nvim which seems to duplicate errors. It also seems to use its own icons (the red and yellow circles).

Update, modifying my gruvbox config to enable transparent_mode, seemed to fix the highlighting issues. Still uncertain how to configure icons correctly though. Not sure if this is still the right issues page to post on for that.

		priority = 1000,
		config = function()
			require("gruvbox").setup({
				transparent_mode = true,
			})
			vim.o.background = "dark" -- or "light" for light mode
			vim.cmd([[colorscheme gruvbox]])
		end,
	},
