This occurs in both Edge (145) and Firefox (148) at the very least, with React 19.
If you have a Redux-based project, and you use it to fire off some events, then open the Inspector and choose the Redux tab, it shows and records events and state correctly.
However, if the Inspector is open and you hit Refresh, you see the first few events come in really quick and then the whole state disappears back to @@INIT. You can then fire off some events, but that first batch are lost, and so you can't see the "at rest" state of the store until you do some other action.
