Release order not sorted by seconds granularity?

I have an action that creates a “v[X.X.X]” release and then “latest” release in separate (consecutive) steps: userscript-github-repository-categories/release-build.yml at 42b75d27386a2863c61a6004415921a4d6ab6950 · Trinovantes/userscript-github-repository-categories · GitHub

However, on my releases page, it tags “v[X.X.X]” instead of “latest” as the “Latest Release”: Releases · Trinovantes/userscript-github-repository-categories · GitHub

Inspecting the DOM, I see that the <time> for “v[X.X.X]” is “2021-05-31T23:05:07Z” whereas “latest” is “2021-05-31T23:05:12Z” (7 seconds later)
