I can confirm this issue. Any thoughts @LeoMcA? Shall I refile this as a yari bug?

Thanks a lot for raising this one. I've moved it into the Yari repo which looks like the right place for this 👍🏻

I see a similar problem in Safari on iOS 17.4

I was able to reproduce the issue locally with Safari 17.4 and confirmed using BrowserStack Live that Safari 16.5 is unaffected, so it looks like a regression in Safari. Here's a screen recording with the DevTools Network tab open:

Unfortunately, I think we have to wait for Apple to fix the bug. I have submitted a report via Feedback Assistant (FB13694054).
