It seems this code makes just 1 snapshot.
so you can change code like below

// fireEvent.click(getByText('inc'))
// fireEvent.click(getByText('inc'))
await waitFor(() => fireEvent.click(getByText("inc")));
await waitFor(() => fireEvent.click(getByText("inc")));

eaa96e4 passes the tests. I'm not 100% sure if there are any other cases that this can't handle, but let's go with this for now.
