Remaining app updates seem to randomly reorder

When updating an app with some other updates pending, the remaining updates reorder kind of randomly after updating the first app.

GitMate.io thinks possibly related issues are #5219 (Updating NC12: update theming app fails ), #5024 (Update fails with OAuth2 app), #7002 (Automatic app updates), #6479 (Failed core update, and app updating issues), and #8929 (Detect if a shipped app is updated and can be updated).
