Click the toggle to show yearly pricing and the url is updated, but you can still press back to go to whatever previous page you visited.
Then, this page DOES update the history stack when the url changes: https://wakatime.com/dashboard
Click the date range and select a new range, notice the url changes but also you can press back to go to your previous date range.
1. Go to page you came from prior to that site
2. Go to the top of the page, stay on the site
If you picked 1, then "without putting it on the history stack" is the correct choice.
