What:
waitForno longer triggers "missing act" warnings when using real timers.Why:
Accomodate reactwg/react-18#102
How:
Run with
IS_REACT_ACT_ENVIRONMENTwhen using ouract.Run without
IS_REACT_ACT_ENVIRONMENTinwaitFor(advancing timers is still wrapped in act to flush updates).I'm quite uncomfortable with the implementation. We need to accomodate thenables in our
actso we have to make sure we're resettingIS_REACT_ACT_ENVIRONMENTnot too early.I didn't enable
IS_REACT_ACT_ENVIRONMENTin our global setup (i.e. the main entrypoint) since that would enable "missing act" warnings in non-jest environments.We probably want to do this anyway but that should be handled in a separate PR since it would be new behavior.
