            Bug ID: 221661
           Summary: WKWebView should provide a way to handle spins
           Product: WebKit
           Version: Safari 14
          Hardware: Mac (Apple Silicon)
                OS: macOS 11
            Status: NEW
          Severity: Enhancement
          Priority: P2
         Component: WebKit API
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: jonathan at tumult.com

There are methods to recover from crashes, but how about exposing a way to kill a WKWebView child that is processing for too long (or manually kill?).

Tumult Whisk [https://tumult.com/whisk/] is an HTML editor with a live preview. Users can easily shoot themselves in the foot by writing <script> code that goes into an infinite loop. It'd be great if there was a proper way to recover from this.  Seems like a missed opportunity/advantage of WKWebView vs. WebView (Legacy).
