This event is emitted after the browser's address bar was updated with a new URL.
There may be several reasons why the browser location was changed:
- A fragment update changes history through navigation or rendering with
{ history: true }.
- The user uses the back or forward buttons in their browser UI.
- Programmatic calls to
up.history.push().
When a layer has no visible history, following a link
will not cause the browser's address bar to be updated. In this case no up:location:changed event will be emitted.
However, a up:layer:location:changed will be emitted even if the address bar did not change.
