What happens during the run is that plotly plots are shown during run on your computer but they don't show in UI and ONLY after the run is finished the plots show up?
Are your runs long?

Updated.
They are rendered on some iterations, especially early iterations. Rest is correct
The testing runs are short but real runs will be long so its very undesirable
Upd: cant reproduce "rendered on some iterations", now its only: not rendered until run is completed.
Upd: fixed the error, it was in some unrelated code
