rust-mode-treesitter-derive with lsp-mode breaks electric-pair-mode

[forgemo]

I noticed that electric-pair-mode stopped working in rust files. After a few hours of investigation, I was able to narrow it down to using treesitter with rust-mode-treesitter-derive.

The difficulty was, that it breaks it only after the second emacs start (after a fresh install).

Here is a minimal example to reproduce the issue:

(require 'package)
(setq package-archives '(("melpa" . "https://melpa.org/packages/")
                         ("gnu" . "https://elpa.gnu.org/packages/")))

(unless (package-installed-p 'use-package)
  (package-refresh-contents)
  (package-install 'use-package))

(require 'use-package)
(setq use-package-always-ensure t)

(electric-pair-mode 1) ;; this stops working after the second emacs start

(use-package rust-mode
    :hook (rust-mode . lsp-deferred)
    :init
    (setq rust-mode-treesitter-derive t) ;; this causes the bug
    :config
    (setq rust-format-on-save nil))

(use-package lsp-mode)

My test protocol was:

1. delete .config/emacs/elpa and .config/emacs/eln-cache folder (i didn't delete the .config/emacs/treesitter folder)
2. Save the above init.el in .config/emacs/init.el
3. Open a rust file emacs main.rs
4. Wait for the packages to get installed
5. Write a few brackets in the rust file to ensure electric-pair is working.
6. Close emacs
7. Open the same rust file again
8. Write a few brackets in the rust file. electric-pair is no more working. 🐛
