fix(react): ensure hitComponent does not remount on rerenders

[aymeric-giraudet]

Fixes #6189

Summary

We should generally avoid defining components inline during render, when wrapping provided components it causes remounts on every render which can be a problem if they are using hooks like useState, useEffect and useRef.

Result

In this case we wrap it with useMemo as we can't just pass it to the UI component as is.
Added tests to make sure they only mount once.
