Severe freeze when typing closing quote with Corfu + lsp-mode + pyright (electric-pair active)

### Thank you for the bug report

- [x] I am using the latest version of `lsp-mode` related packages.
- [x] I checked [FAQ](https://emacs-lsp.github.io/lsp-mode/page/faq/) and [Troubleshooting](https://emacs-lsp.github.io/lsp-mode/page/troubleshooting/) sections
- [ ] You may also try reproduce the issue using clean environment using the following command: `M-x lsp-start-plain`


### Bug description

### Environment
- Emacs version: GNU Emacs (native-comp, latest stable)
- Packages: `corfu` (latest) + `lsp-mode` (latest) + `lsp-pyright` (latest) + `electric-pair-mode` (builtin, enabled)
- Language: Python (pyright as LSP backend)

### Problem Description
**Critical freeze (UI unresponsive) occurs every time** I type a closing double quote `"` in Python code (e.g. typing `print("hello"` → `electric-pair` auto-inserts `")` and places cursor at the closing `"` position.
- No completion is being used/invoked manually at all, the freeze happens purely on typing the quote (automatic pair insertion)
- Freeze duration is noticeable (5-10s) with 100% CPU spike in Emacs main thread
- This also sometimes happens at ( when typing print(

### Full Configuration
```elisp
;;; corfu completion
(use-package corfu
  :ensure t
  :init (global-corfu-mode)
  :custom
  (corfu-min-prefix-length 1)
  (corfu-auto-delay 0.3)
  (corfu-cycle t)
  (corfu-align-to-window t)
  (corfu-popupinfo-delay '(0.5 . 0.2))
  (corfu-preview-current nil)
  (corfu-auto t)
  (corfu-quit-no-match t)
  :config
  (corfu-history-mode 1)
  (corfu-popupinfo-mode))

;;; lsp mode
  (use-package lsp-mode
  :ensure t
  :defer t
  :init
  (setq lsp-keymap-prefix "C-c l")
  :hook
  (lsp-mode . lsp-enable-which-key-integration)
  :commands (lsp lsp-deferred)
  :custom
  (lsp-completion-provider :capf)
  (lsp-headerline-breadcrumb-enable t)
  (lsp-log-io t)
  :bind
  ("C-c l s" . lsp-ivy-workspace-symbol))

;;; pyright
(use-package lsp-pyright
  :ensure t
  :defer t
  :after lsp-mode
  :hook (python-mode . (lambda ()
                         (require 'lsp-pyright))))
```
### lsp-io-log
in lsp-log there would be lost of request and cancle during freeze time which is so long to privide.
### besides
the freeze dispears when i close corfu-auto, but auto complete helps me a lot so i do not wants to close it.
thanks for responding and answering

### Steps to reproduce

- config corfu lsp-mode lsp-pyright
- print code
```
print("hello")
```


### Expected behavior

the completion of print or sign not freeze the gui.
or the freeze time is below 1s which was show in lsp-log instead of freeze 10s

### Which Language Server did you use?

pyright

### OS

Linux

### Error callstack

```emacs-lisp
lsp log was too long so i split half to additional context
the backtrace maybe wrong

Debugger entered--Lisp error: (quit)
  syntax-propertize(8)
  syntax-ppss(8)
  electric-pair--unbalanced-strings-p(34)
  electric-pair-inhibit-if-helps-balance(34)

  self-insert-command(1 34)
  funcall-interactively(self-insert-command 1 34)

the freeze was hard to get backtrance so this backtrance maybe wrong
# lsp-log
- the lsp log the freeze happens mainly after 12:05:01
