How to keep the current page/view when lazy loading?

I do not know whether it is possible to instruct Suspense to use the current page/view as the fallback component until the next view is ready to be rendered.

Indeed, in order to achieve YouTube or GitHub like loading with a top linear progress bar on the current view, we need a way to instruct the Suspense component to not unmount the current view straight away or to just add an additional child component to the current view.

The documentation would benefit from adding such example, as this behaviour is now the industry norm and it greatly improves the UX. As on StackOverflow and other relevant forums no one seems to know how to do:

However, I am not sure this is possible right now, and if not putting it on the backlog as a new feature will be useful.

Commencez par examiner le comportement de Suspense décrit dans l'issue et les deux discussions liées afin de déterminer si la vue actuelle peut rester montée pendant le chargement différé. Documentez le comportement pris en charge avec un exemple de chargement si possible, ou précisez que le comportement de fallback demandé n'est actuellement pas disponible.
