/*
 * next/compat/router is used so that this doesn't cause an error on App
 * Router builds. However, no replacement for the functionality is provided if
 * the router is missing (it just silently fails).
 *
 * This is fine because docs (the only site moving to App Router right now)
 * doesn't use this hook. Skipping it silently is less troublesome than trying
 * to make it work across both routers -- making search params work seamlessly
 * is a giant pain, and too much critical studio functionality depends on this
 * to mess with it lightly.
