Screen recording demonstrating pinch gesture closing ARQL window

Observations:

When viewing a 3D model in AR QuickLook, some gesture interactions cause the entire ARQL window to start minimising and eventually closing the session window altogether. 

If user performs a pinch closed gesture to scale the model down, the ARQL window closes. But user is able to perform a pinch open gesture to scale model up, and this works fine. 

Also, if user performs a drag down gesture, to move the model closer on the horizontal plane, the ARQL window closes. But user is able to perform drag up / left / right gestures to move model, and this works fine. 


Expected Results:

User should be able to pinch (to scale down) or drag downwards (to reposition model) without exiting ARQL session. 

Repro steps:

* Using iOS 18 beta
* In Safari, visit: https://developer.apple.com/augmented-reality/quick-look/
* Select a model to view in ARQL
* Once model is anchored, pinch model to scale down
* Observe the model does not shrink, but the entire ARQL window shrinks
* Continuing to pinch will eventually minimise the ARQL session window altogether, returning user to originating webpage
* Alternatively, open 3D model, once anchored, drag downwards to reposition, and observe ARQL screen minimises and closes

Note that when performing the same interactions with third party browsers such as Chrome and Edge, the issue is not observed.
