usePolled reports when a request is in flight (through a new onBusy of the poller) and holds it on for at least 0.4 seconds, so a quick answer still reads as a refresh. The picker swaps its clock for the spinner, in the same box so its width stays, and the spinner stands still where motion is off. Every page with a picker passes it; a page with several polled requests shows it while any of them runs. The Jobs page fetches through shared components and has none yet.
