Why are TypeScript files with shebang in nvim rendered in gray?

I have installed the up-to-date tree-sitter-typescript, and it works well in typescript files without shebang.

I searched online but couldn't find any particularly similar questions. Some people reported that their treesitter was not functioning properly, but mine was able to parse the AST correctly:

Here is my treesitter config:

{ highlight = { enable = true, }, ensure_installed = { "c", "cpp", "lua", "vim", "vimdoc", "regex", "markdown", "markdown_inline", "latex", "javascript", "json", "typescript", }, incremental_selection = { enable = true, keymaps = { init_selection = "<CR>", node_incremental = "<CR>", node_decremental = "<BS>", scope_incremental = "<TAB>", }, }, }
