@stipsan found this issue where the compiler would bailout on the
`useLayoutEffect` examples in the React docs. While setState in an
effect is typically an anti-pattern due to the fact that it hurts
performance through cascading renders, the one scenario where it _is_
allowed is if the value being set flows from a ref.
