After some debugging I figured out that it can be only reproduced when 
`eglot-ensure` is added to `typescript-ts-mode-hook` and 
`tsx-ts-mode-hook`. So, steps to reproduce are the following:
- Optionally install `typescript-language-server` (if it's not 
 installed there will be eglot error, but the original issue will 
 still be reproducible).
- `emacs -Q`
- evaluate the following:

(require 'typescript-ts-mode)
(require 'eglot)
(add-hook 'typescript-ts-mode-hook #'eglot-ensure)
(add-hook 'tsx-ts-mode-hook #'eglot-ensure)

- open attached tsx file.
