on iPadOS 15.5 public beta

- I interact with one of two model elements (rotate, scale)
- I scroll down to the second model element and try to interact with it
  - This fails because a single finger gesture is mis-interpreted as a multi finger gesture.
- I scroll up to the first model and now my single finger gesture is totally ignored (assuming that it is interpreted as a three finger gesture)

My assumption is, that the scroll gesture also messes with the stream of communication to the connected ARQL process, similar to https://bugs.webkit.org/show_bug.cgi?id=237950

I restructured my DOM and with <model> not nested inside other divs, and cannot reproduce the reported problem any more. It also avoids placing UI over the <model>.

I now provide both versions on our server:

Safari on iPadOS 16 beta
now doesn't even load the first .usdz
Both <model> areas just show a small ARKit icon with a close x

Suggestion: make the icon look more as a strike thru instead of an invite to press close
