I am trying to update the URL without re loading the whole page. I have a dropdown that controls the data on the screen and the selected value for this dropdown is passed through the URL. If there is no value passed the user is prompted to select a value.
User navigates to the page with specified value "Example1"
The user then selects Example2 from the dropdown.
If they click browser back button, it should take them to Example1
If they click browser refresh, it should show Example2
What actually happens is
Back: whatever page you were on before navigating to my page
Refresh: goes to Example1
Previously in 8.3 I was able to solve these problems using history.pushState
