I think it could be fine to keep this regardless.

Fine to keep but probably not needed?

Otherwise, is there a point to do the config?

The idea is that maybe there's remaining time after the first preview rendering but not enough to render the next one, so the "once" force us the priority queue to schedule an update for later, give a decent amount of time for the browser for potential "interactions" that may come during the first rendering or a bit after but before the next "idle callback". The ultimate goal to reduce the lags as much as we can.

@youknowriad Do you agree with the naming? Should we call it something else? Or make it private?

The naming is fine by me and also public is fine. Should we pass the option as true for the "Async" component queue?
But I do wonder if it should be a global option like here or an option per callback (on the add function).

Whoops, reverted a bit too much in 9190404. Added it back.
I think a "global" option makes sense. I can't think of a case where you'd want to use it for some callbacks and not others? If you really need that separation, you could make two queues?

@youknowriad Should we still do this, or close it? |

I don't know, I feel like we don't have enough validation about whether this improves things. So maybe we should not do it for now? WDYT |

What?
This is an idea from @youknowriad #60425 (comment)
Basically instead of running multiple priority queue callback in one idle callback and checking idle time remaining,
forcing us to render sync, we could try an option to force one callback per idle callback.This would prevent multiple previews sneaking into a single idle callback, theoretically reducing lag.
The question is if the browser actually waits for the async rendering by React until it run the next idle callback. In my testing, it seem to. I wonder if @oandregal tests any regressions from #60425 with this PR.I want to also look in @jsnajdr because he initially fixed async list in #48238 (reported by @fullofcaffeine). We could check if #48085 doesn't regress. In my testing, image patterns still render one by one after searching for them in the inserter.Why?
How?
