While testing some scripts to automate collecting updated plugins and their versions for our configuration management I wanted to make sure the scripts were idempotent or at least consistent in upgrading everything with an available update that wasn't pinned. To do so I performed a manual downgrade of several plugins through the UI (they were updated from the initial config managed versions by my script) but noticed that on the /updateCenter page I was brought to after clicking 'Downgrade' that the status after downgrading was "Success", with no mention of the restart that IS required to make the downgrade(s) actually take effect. I tested downgrading a couple other plugins with the same result. Navigating to the /pluginManager page I saw that it did have a note at the bottom that an operation was 'awaiting restart' but going to the "pending operations" aka /updateCenter page it simply showed the "Success" status and still no suggestion that the restart was required though the checkbox to restart when no jobs were running was present and usable.
