<div> <button id="mybutton1" type="button"> Change location </button> </div> <script> function MyClick1(event) { location = "https://underpassapp.com"; } document.getElementById("mybutton1") .addEventListener("click", MyClick1); </script> In Firefox and Chrome this creates a a new history item, in Safari this doesn't. Perhaps https://wpt.fyi/results/html/browsers/browsing-the-web/navigating-across-documents/replace-before-load?label=master&label=experimental&product=chrome&product=firefox&product=safari&aligned&q=location-setter, but likely we have some WPT coverage for this.

I am unable to reproduce. When I click the button, I see history.length increase by one and there is an option to go back in the Safari UI.
I see this was reported on macOS 10.13 High Sierra which is super old. I am on macOS 12.1 Monterey so this could be why I cannot reproduce.
(In reply to Chris Dumez from comment #3) > I see this was reported on macOS 10.13 High Sierra which is super old. I am > on macOS 12.1 Monterey so this could be why I cannot reproduce. The post says "This bug appears to be many years old: it occurs in the latest version 15.1, and it occurs in the oldest version that I could test, Safari 11 on macOS 10.13 High Sierra." Certainly I can reproduce it on 12.0.1 (21A559), but I don't have 12.1 immediately to hand.

Chris I think you were testing the wrong thing. This is about browser global history, not session history.
This blog post that spawned the radar mentioned that, not sure why that wasn’t included in the report https://lapcatsoftware.com/articles/history.html
And on that note, this may be WebKit not sending a sensible history delegate message to Safari, or it might be Safari mishandling it. Investigation will be needed.
