Leaving a short note here for future reference, since my original PR description was quite minimal.

The issue was introduced in PR #61054, and at the time that PR work was completed (early February) we didn't yet have the relevant CI check in place.
When that PR was merged today, it ended up breaking the overall CI, and in the resulting urgent situation the fix was applied at committer level across two follow‑up PRs (PR 63403 and PR 63404).
