wait for the daily set panel to fill before checking it

The panel hydrates progressively, so waiting for the section only tells you it opened, not that it filled. A check running on the first non-empty state reports whatever happened to be rendered at that moment, which is why the daily set came out differently run to run. Same wait as complete_bing_daily_set: hold out for the full set, report what is there if it never arrives.
