inlay hints only show after buffer change (rust-analyzer)

[pid42]

I have a quite vanilla emacs29/eglot configuration for rust
If a open a rust file, I noticed that the inlay hints will only show after I modify the opened file.
I could not find any documentation anywhere that would justify that.
Does anyone else noticed the same.

I'm running Emacs 29.4 on MacOS (but the same is happening on my linux machine) .
My emacs config, as I said, is quick vanilla. I did not customize anything (no melpa packages).
My config is currently like the following:

(use-package eglot

  :config
  (add-to-list 'eglot-server-programs
	       '(rust-ts-mode . ("rust-analyzer"
				 :initializationOptions
				 (:check (:command "clippy")))))

  )

(use-package rust-ts-mode
  :hook
  ('rust-ts-mode . 'eglot-ensure)
   
  
  :init
  (add-to-list 'auto-mode-alist '("\\.rs\\'" . rust-ts-mode))

  )

But, if I remove it all, open emacs, load a rust file, call rust-ts-mode and then call eglot-mode , I get the same behavior.
