Setting atom from an effect concurrently with another update loses the value
See original GitHub issuePotentially, similar to #728.
Setting atom value inside an effect (via setSelf) while another update is happening loses the state change. Delaying setSelf via window.requestAnimationFrame solves the issue.
Here is the reproduction case I have: https://codesandbox.io/s/xenodochial-firefly-wny9s?file=/src/App.js
- Click “Navigate!”. Observe that “State A” value is empty and “State B” is “hello”.
- Now reload page in the embedded browser with
?delayadded to the URL. - Click “Navigate!”. Observe that “State A” value is now correct (“from effect”) and “State B” is “hello”.

Found the issue, thanks for the great repro @idubrov! I have a fix in the works, though may be delayed through reviews due to holidays…
@mdlavin - Thank you very much for the test case! Yes, I suspect this test is unrelated to the original issue here.
