rustc 1.79.0 commit hash 129f3b996 not found in repo

[xSetech]

I am using this version of rustc:

% rustc --version
rustc 1.79.0 (129f3b996 2024-06-10)

I cloned the Rust repo:

git clone https://github.com/rust-lang/rust.git

I am unable to checkout the commit corresponding to the installed version of rustc:

% git checkout 129f3b996
error: pathspec '129f3b996' did not match any file(s) known to git

rustc --version --verbose:

I am able to find the commit by searching for it on GitHub via the UI:

Note the message at the top:

This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.

It appears the commit was part of PR #126219, see the message:

bors merged commit 129f3b9 into rust-lang:stable on Jun 10

I would expect the commit hash provided by rustc --version to be retrievable from any clone of the repo.
