Behaviour on iOS Safari 16

Not having this property makes pull to refresh actions on web apps not work at all, and also makes several apps (such as a drawing pad) unusable.

Please consider adding support like chrome has:

Here's a demo:

I've also attached a video of the behaviour on different browsers for your reference.

Thank you.

Thank you for the report!

This report is about iOS 16, but I'm seeing the same on iOS 18 beta. I do not know if this is a bug or intentional behavior.
