HLS Pathway Cloning Support

What is the first version of iOS to support pathway cloning as part of content steering? Is it supported in safari browsers via the html video tag?

I can switch between pathways defined in the manifest file, but when I try to clone a pathway and introduce a new pathway id my stream stops.

I believe the first iOS version that supported pathway cloning was iOS 15.4 I am not sure about Safari support.

And the first macOS version to support pathway cloning?
