we write history and then trigger ajax call? Trying to understand how it works now :)

Yeah it's slightly confusing. The links are no longer remote; the new JS code captures the click, pushes the history state and returns false so the click doesn't go through. Then because of the History change, statechange is called and we fetch the last URL via Ajax and update the page.

Otherwise the unobtrusive Rails JS would handle the remote link via AJAX, but then so would the History event, so it was loading twice.
