Hi there forum, I'm having an issue with the following javascript xhr request only in iOS 14 (it works in iOS 13 and lower):      let script = """     var xhr = new XMLHttpRequest();     xhr.open('GET', '\(absoluteUrl)', true);     xhr.responseType = 'blob';     xhr.onload = function(e) {       if (this.status == 200) {         var blob = this.response;         var reader = new window.FileReader();         reader.readAsDataURL(blob);         reader.onloadend = function() { window.webkit.messageHandlers.readBlob.postMessage(reader.result);         }       }     };     xhr.onerror = function(e) {       console.log(e.target)     }     xhr.send();     """           self.webView.evaluateJavaScript(script, completionHandler: nil); The absoulteUrl in question here looks like this: blob:http://{my-host-domain}/1cbb6855-2402-4411-adc7-f889cdd5b78a This blob is always on the same domain that I am navigating to but I've also tried adding app-bound domains to no avail. Is there something about iOS 14 that would make this script break?
