            Bug ID: 272295
           Summary: WKWebView sometimes experiences continuous white
                    screen until the app restarts to load the page
                    normally.
           Product: WebKit
           Version: Safari 17
          Hardware: iPhone / iPad
                OS: iOS 17
            Status: NEW
          Severity: Critical
          Priority: P2
         Component: WebCore JavaScript
          Assignee: webkit-unassigned at lists.webkit.org

Our app occasionally experiences a persistent white screen issue when loading H5 pages using WKWebView. Once this persistent white screen problem occurs, all subsequent WKWebView loads also result in white screens. Upon investigation through console logs, we found that the WKWebView delegate method "didCommitNavigation" is being executed, but the delegate methods "didFailNavigation" and "didFinishNavigation" are not. Additionally, network connectivity has been verified as normal. It feels like JavaScript is stuck in this scenario.

We also found the following suspicious logs in the console:
1、Should process URL called
2、Fetching native takeover URLs
3、Native takeover URLs fetched
4、URL shouldn't be processed
5、Failed to request allowed query parameters from WebPrivacy

Could you please help identify the causes behind the issues described above, and suggest any effective approaches our app can take to resolve or mitigate such problems?

Thank you.
