            Bug ID: 226265
           Summary: Safari iOS ignoring URL fragment parameters when
                    opening USDZ as BLOB in AR QuickLook
           Product: WebKit
           Version: Safari 14
          Hardware: iPhone / iPad
                OS: iOS 14
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: New Bugs
          Assignee: webkit-unassigned at lists.webkit.org

In iOS Safari, when opening an AR QuickLook preview session, it is possible to provide a BLOB as the source USDZ. However, any additional URL fragment parameters appear to be ignored by the QuickLook session.

For example, appending the fragment #allowsContentScaling=0 should prevent the AR model from being scaled by the user. When provided as a URL fragment with a source USDZ URL, this is respected in Quick Look. However, when providing a BLOB as the source, the same parameter is then ignored and the user is able to scale the object. 

It appears that this is the same for any of the supported AR QuickLook parameters, including: allowsContentScaling, callToAction, checkoutTitle, checkoutSubtitle, price, applePayButtonType, custom, customHeight, canonicalWebPageURL.
