Thank you for such detailed report, yet it is strange! Just checked on Sonoma with Chrome 155, and it works for me! Something on your side? Maybe an issue with the cache? It seems like it’s broken on cache check. Try force reloading (ctrl+shift+r) here or on the actual iframe html page: https://html-classic.itch.zone/html/19887746-2169140/.build/index.html?v=1792504733
