Bug: useOptimistic hook showing stale values

[CodingReaper1]

React version: "^18" I tried on "^18.3.1" as well

The current behavior

Number and button appears for like 0.1 second and then dissapears
first i had this setup with database and little more complex ui then i reduced it to very simple arrays with number and button
Btw i did try this with useTransition as well neither that neither action works

The expected behavior

Number with button should appear without dissapearing

What do you expect to happen? You don't have a non-optimistic to actually track persistent state, nor do you have async work.

@vezaynk I expected component to show up and do not dissapear, I did have async work before I changed it to this simple array it was no different from what happening now, am I missing something? can you show me some code example or explain more what should be done?

@CodingReaper1 useOptimistic values are discarded after a transition has completed.optimisticNumbers will only show the optimistic result while the operation is running.

Once it has completed, non-optimistic state is expected to either catch up or be canceled.
