Use history.replaceState instead of pushState: https://developer.mozilla.org/en-US/docs/Web/API/History_API

That will still change the address in the location bar without filling up the history so it takes many back button clicks to leave.

Matt, you have been downgraded to a 1. :)

Actually I read this wrong. We decided on pushState deliberately, since it’s essentially a form submission, and so a history entry.

That said, one of our folks suggested same so I think from a UX perspective, we could go either way. It doesn’t _feel_ like a form submission, one could argue.
