            Bug ID: 238316
           Summary: [Model] Standalone model document window resize
                    changes camera lookAt and moves 3D asset out of sight
           Product: WebKit
           Version: Safari Technology Preview
          Hardware: Mac (Apple Silicon)
                OS: macOS 12
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: New Bugs

I tested r142 on macOS12.3 with a standalone model document loaded from this URL: https://kreativekk.de/wp-content/uploads/ar/K3-CNC-Demo.usdz

Resizing the window showed unexpected behaviour:

When the height is changed, the 3D asset is not kept in the camera center and can move out of sight.
Same for a window width below the default <model> width, but both horizontally and vertically.

While testing, SafariTP r142 crashed twice as reported separately.
