 - It references a property of `url` (such as `url.pathname` or `url.search`) whose value has changed. Properties in `request.url` are _not_ tracked
 - It calls `url.searchParams.get(...)`, `url.searchParams.getAll(...)` or `url.searchParams.has(...)` and the parameter in question changes. Accessing other properties of `url.searchParams` will have the same effect as accessing `url.search`.

 - All active `load` functions were forcibly rerun with [`invalidateAll()`](modules#$app-navigation-invalidateall)
