In a shallow clone, `git fetch` may fail to apply thin packs due to missing base objects. We typically don't notice this with first-parent commits and prospective merge commits, but it seems fairly common with arbitrary PR-branch commits. In this instance we don't need the full commit data, we only need to apply its diff as a patch. So fetch the diff from GitHub's API and apply using `git apply`. This partially reverts commit 4787f35

#480395 does not seem to be enough to resolve CI issues for #480141, yet. Despite testing #480395 thoroughly, it seems that in #480141 we run into issues with shallow clones, thin fetch-packs, and missing base objects:
