Can I use indexedDB in a cordova iOS application?

Question

I'm getting an InvalidAccessError when I try to open a Indexed Database in my cordova iOS application.

Platform:

• cordova: 5.4.1
• cordova-ios: 4.0.1
• iOS 9.2 (simulator and real device)

I already added the Plugin to use the WKWebview which made the the indexedDB object at least defined, but the error is thrown. The code works in chrome, safari and mobile safari if I run it via cordova's own web server.

config.xml looks like this

<content src="index.html" />
<plugin name="cordova-plugin-whitelist" spec="1" />
<access origin="*" />
<allow-intent href="http://*/*" />
<allow-intent href="https://*/*" />
<allow-intent href="tel:*" />
<allow-intent href="sms:*" />
<allow-intent href="mailto:*" />
<allow-intent href="geo:*" />
<platform name="android">
    <allow-intent href="market:*" />
</platform>
<platform name="ios">
    <allow-intent href="itms:*" />
    <allow-intent href="itms-apps:*" />
</platform>
<feature name="CDVWKWebViewEngine">
    <param name="ios-package" value="CDVWKWebViewEngine" />
</feature>

<preference name="CordovaWebViewEngine" value="CDVWKWebViewEngine" />

and I try to open the indexedDB with this:

openDb: function() {
    var openRequest = window.indexedDB.open(DB_NAME, DB_VERSION);
    openRequest.onupgradeneeded = function(event) {
        console.log('upgrade needed');
        console.log(event);
        myIndexDb = event.target.result;
        var options = {
            autoIncrement: true,
            keyPath: 'key'
        };
        var objectStore = myIndexDb.createObjectStore(DB_STORE_NAME, options);
    };
    openRequest.onerror = function(event) {
        console.log(event);
        console.log('indexDB open Error!');
    };
    openRequest.onsuccess = function(event) {
        console.log('open success');
        myIndexDb = this.result;
    };
    openRequest.onblocked = function(event) {
        console.log('request is blocked');
        console.log(event);
    }
}

At the moment it works with the Telerik Plugin https://github.com/Telerik-Verified-Plugins/WKWebView (and cordova-ios 3.9.2)
