            Bug ID: 236069
           Summary: Safari 15 -> QuickLook - model not loading when
                    passing extra parameters
           Product: WebKit
           Version: Safari 15
          Hardware: iPhone / iPad
                OS: iOS 15
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: New Bugs

On iOS 15.2 when passing USDZ from Safari to QuickLook AR, as a blob with parameters (eg. fixed scaling), the model is never rendered.
The loader spinner keeps spinning infinitely.

You can repro the bug here:

Built using model-viewer.dev component. USDZ is generated on the fly.
I believe model-viewer's 'fixed scaling' is translated as #allowsContentScaling=0
Without the parameter models loads as expected.
