Noice supports syntax highlighting for the command line (which is nice!), but apparently does so by setting the filetype -- which triggers all manner of autocommands, such as attaching a language server.

Instead, Noice should just set vim.bo.syntax directly, or -- since Noice only supports treesitter highlighting, IIUC -- use vim.treesitter.start(bufnr, language).

(Compare how telescope does this, which has the same issue with its previews.)
