            Bug ID: 271701
           Summary: REGRESSION: Apple Pay button fails to render when
                    opening AR QuickLook with USDZ blob
           Product: WebKit
           Version: Safari 17
          Hardware: iPhone / iPad
                OS: iOS 17
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: New Bugs
          Assignee: webkit-unassigned at lists.webkit.org

In iOS 17.4.1, when opening a USDZ blob to view in AR QuickLook, and passing in Apple Pay # params, such as applePayButtonType / checkoutTitle / checkoutSubtitle / price, the Apple Pay banner is not rendered. 

In previous versions of iOS, this used to be possible. 

Also, when opening USDZ blob, it is still possible to use other # params such as allowsContentScaling / canonicalWebPageURL and most significantly, custom / customHeight parameters do still render a custom banner in the AR session.

Repro steps:
- Using iOS 17.4.1 iPhone
- Visit this test: https://modelviewer-extended-params.glitch.me/ (This link uses the ModelViewer component to generate a USDZ blob from GLB). 
- Turn ON 'Auto USDZ' option to use USDZ blob rather than the USDZ file. 
- Turn ON 'QuickLook Apple Pay Button' option to add # params.
- Tap the AR icon to open model in AR QuickLook.
- Observe, no Apple Pay banner.


Tested with:
- iOS 17.4.1 - FAIL
- iOS 17.2.1 - FAIL
- iOS 16.6.1 - PASS
- iOS 15.8.1 - PASS
