On iOS 15.4, the following code loading a local .log file (works on iOS 15.2.1) stops working.

```
let url = Bundle.main.url(forResource: "ABC", withExtension: "log")!
webView.loadFileURL(url, allowingReadAccessTo: url)
```

Some logs:
```
[Process] 0x7fa558809220 - [pageProxyID=6, webPageID=7, PID=81527] WebPageProxy::didFailProvisionalLoadForFrame: frameID=3, domain=WebKitErrorDomain, code=102, isMainFrame=1
```

Error object in func webView(_ webView: WKWebView, didFailProvisionalNavigation navigation: WKNavigation!, withError error: Error)
```
Error Domain=WebKitErrorDomain Code=102 "Frame load interrupted" UserInfo={_WKRecoveryAttempterErrorKey=<WKReloadFrameErrorRecoveryAttempter: 0x6000000a2120>, NSErrorFailingURLStringKey=LOG_FILE_PATH, NSErrorFailingURLKey=LOG_FILE_PATH, NSLocalizedDescription=Frame load interrupted}
