According to our crash analytics, our application crashes while a context menu is opened on a web view. This crash takes place on iOS 26+ only.
The messages states that a web view is no longer inside active window hierarchy, however we doesn't modify web view instance's parent anyhow while the context menu is opened.
Can you please help with a fix or at least workaround for this issue? What's your opinion for bug localization (application or framework)?

NSAssertFile = "UITargetedPreview.m";
