If do not check it and try use this hook with blur, handleChange will never be called, because ownerDocument.activeElement will be always ownerDocument.body.

Hi.
I covered all the hooks with tests, except for
useIsomorphicLayoutEffect(I have no idea what and how to honestly test there). I don’t see the point in covering individual helpers within this task with tests, mostly they are too simple and/or do not rely to React.In some hooks, I found problems that I fixed:
useFocusChangethat commented below;useLazyRef- unnecessarily usedany;useUpdateEffect- the cleanup return from the effect was missed, the effects were not cleaned.I also checked the work of all tests in
StrictMode(includingreact@18). One of the hooks required a rewrite - this isuseUpdateEffect. Now it works as intended.
