If you wrap console.log with useEffect and the result is something expected, then it's not an issue, but an intentional behavior to make it better work with concurrent react.

I probably understand, thanks~

I understand the different behavior in React 18 and 17. #1158 (comment)

#1159 will improve the behavior, it doesn't re-render on updates. (on mount, it's double render with one commit.)
