[LiveComponent] URL linked LiveProps don't seem to honour the browser back button

[toby-griffiths]

We have a live component that maps it's #[LiveProp] to a URL parameter, which we use to determine which child components to display on the page.

This works find, but when we use the browser back button to navigate back to the previous "page", it doesn't navigate back, and pressing a second time returns to the page prior to the previous one.

Is this expected bahaviour, or is this a bug? I'm happy to create a reproducer if this is not expected behaviour.

Thanks.

Having dug a little more it looks like the live_controller uses history.replaceState(), rather than history.pushState(). Is there a reason for this? Manually overriding this in my project allows for the updating of the URL using the back button, but I think more would be needed to get it to udpate the live component state?

And here's the reproducer I created to test…
