Alas, that test failure is the same one I was trying to fix in #10118, so I guess we're back to where we started. |

Because useSyncExternalStore does not call the subscribe function until an internal useEffect fires, there's a real chance the latest data from the cache have changed in the meantime, so it's not useless to check for changes right away and potentially call forceUpdate. Passing immediate:true to cache.watch ensures the callback will be called right away, rather than the _next_ time relevant data change.

useFragmenttest has been failing locally for me and has even failed onmainfor otherwise innocuous commits like 2db905f (failing CI job).I added this
Promiselogic in #10118 to fix another flakiness issue, but the current state seems worse (more frequent failures) than before.
