How to make Emacs use ELPA version of `compat'?

Hello, everyone.

First time requesting for help in Emacs mailing list.

I am using Vertico (https://github.com/minad/vertico) for minibuffer 
completion. Recently, a new commit that requires `compat' version 31 
(namely, the `set-local' function) was introduced.

Naturally, I opened up the package list menu, marked `compat' for 
update, and performed upgrade procedure just like other ELPA packages.
(Note that I already have `package-install-upgrade-built-in' set as t.)

However, upon running `restart-emacs', it seems that Emacs is loading 
the built-in version (30.2.9999) even though I installed the newer 
version already.

I've checked the contents of `load-path' and the package menu, but both 
look fine to me. The newer version appears before system elisp 
directory, and the package info page says that `compat' is "installed" 
and "shadowing a built-in package".

To enable the newer version, I need to click the correct version in the 
package info page and re-install.

Is there a way to make Emacs always prefer the version from ELPA?
