It was working for me in iOS 26.1. Then it stopped working in 26.2 again. I just reported it again. Here' my number: FB21204628

I feel like that would be an awesome feature to include directly in WebKit. Maybe I'm thinking about it incorrectly though. Maybe it does make more sense to be a part of the browser instead of the engine it runs on. Thanks for your reply anyhow.

I appreciate your response and that's interesting that it could be one case that has the clue needed to solve the bug. I did indeed file a bug: FB18029135
