Unable to pass format options to tsserver

[nicolas-martin]

I'm trying to set my project like this

require("typescript-tools").setup {
	on_attach = on_attach,
	capabilities = capabilities,
	settings = {
		-- IT DOESN"T WORK!
		tsserver_format_options = {
			indentSize = 4,
			tabSize = 4,
			convertTabsToSpaces = false,
		},
	},
}

My autocmd is as follows:

autocmd("FileType", {
	pattern = { "rust", "javascript", "typescript", "typescriptreact", "proto", "yaml", "lua", "javascriptreact" },
	callback = function()
		vim.opt_local.tabstop = 4
		vim.opt_local.shiftwidth = 4
		vim.opt_local.softtabstop = 4
		vim.opt_local.expandtab = false
		vim.opt_local.signcolumn = "yes"
	end,
})

I can validate with LspLog that it passes the argument correctly

[DEBUG][2025-03-18 09:51:17] ...m/lsp/client.lua:678	"LSP[typescript-tools]"	"client.request"	3	"textDocument/formatting"	{  options = {    insertSpaces = false,    tabSize = 4  },  textDocument = {    uri = "file:///Users/nma/dev/dankfolio/frontend/src/components/CoinCard.tsx"  }}	<function 1>	3

Verified that they are the correct options in tsserver also.

But somehow whenever I do redraw! I can see the \t but they get replaced as soon as I format the file.

I'm not sure what I'm doing wrong here.
