 It's possible to hook this up with events from a page-level transition component to make the scroll behavior play nicely with your page transitions, but due to the possible variance and complexity in use cases, we simply provide this primitive to enable specific userland implementations.

+## Smooth Scrolling
+
+You can enable native smooth scrolling for [browsers supporting it](https://developer.mozilla.org/en-US/docs/Web/API/ScrollToOptions/behavior) by simply adding the `behavior` option to the object returned inside `scrollBehavior`:

+```js
+scrollBehavior (to, from, savedPosition) {
+  if (to.hash) {
+    return {
+      selector: to.hash
+      behavior: 'smooth',
+    }

Subject: [PATCH 3/5] fix(encoding): decode params (#3350)

* fix(encoding): decode params

This change forces users to encode their `path` in routes but also fixes
existing problems with route location that were provided as string and
not encoded. Specially with the slash character, allowing it to be
encoded and decoded properly.

* feat: warn against unencoded routes
