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.
