Safari can't open Restricted pages when SharedArrayBuffer support is enabled

[N-Carter]

I have an in-progress Godot 4.1.3 game which I'm building as HTML5 as that's the easiest way to get people to test it as it develops. I wanted to try hosting it on Itch in Restricted mode in order to have password protection.

This works on all browsers except Safari. I notice Safari redirects games which use SharedArrayBuffer to a new URL to work around a missing cross-origin isolation feature, as described in this post:

This does work if the page is not Restricted. If it is Restricted, it redirects to a 404 error instead.

As a workaround, I've set my game's page to Public mode, made it unlisted and hid it from my page. Let me know if you'd like me to set it back to Restricted and provide a link for testing.
