I'm getting the following crash reports on iOS version 15.2 through 15.6 on iPhone/iPad.
I actually can't reproduce the crash but have plenty of reports crashing WebCoreResourceHandleAsOperationQueueDelegate.mm:341.
The app loads multiple hidden web views simultaneously and then shows a successfully loaded view.
