Created attachment 458101 [details] Code reproduction Dragging and dropping a link in a webview on iOS 15 causes a UIDragInteraction soft assert to be logged. The full message reads: [Assert] CLIENT APP ERROR - Neither the view or container of the UITargetedPreview is currently in a window. This is in violation of UIDragInteraction API contract and can cause a severe visual glich. THIS IS A CLIENT APP BUG and will soon be a hard assert. PLEASE FIX ME Steps to reproduce: 1. Download attached code reproduction. 2. Open code reproduction in Xcode and deploy to a device running iOS 15. 3. Drag and drop the "A simple link" link. Observe that the sort assert is logged to the Xcode console. Expected Behavior: I would expect that no assert is logged when dragging and dropping. Actual Behavior: An assert is logged when dragging and dropping. Other Information: I tested this on a device running iOS 15.4.1.
