Bug 259141

Summary: REGRESSION: Safari 17 fails to open USDZ blob in QuickLook
Product: WebKit Reporter: Miles <mail>
Component: New BugsAssignee: Nobody <webkit-unassigned>
Status: RESOLVED DUPLICATE

Description Miles 2023-07-12 01:47:11 PDT 
Observed on iPhone 12 Pro, iOS 17 Beta 3, (21A5277h)

When opening USDZ file blob from Safari, QuickLook opens momentarily with blank screen then closes back to Safari immediately.

Opening USDZ from full URL still works fine, 3D model is displayed in AR.

Note that opening USDZ file blob from Chrome on same device still works, 3D model is displayed in AR.

So it appears to be a Safari regression, handling blob urls?

Select a material variant. Tap the AR icon. Tis will attempt to open a USDZ blob in QuickLook.
