[SOLVED] KlarnaHybridSDK - Getting swamped with the message "Notifying Native Hook" [ANDROID]

Problem description

When debugging the web portion of my app either in chrome://inspect/#devices or directly in android studio I can see that I'm getting swamped with the message "Notifying Native Hook". When using chrome://inspect/#devices to inspect the web page used in the app I see that the message has the source VM298:5 (quite sure that I've seen it with another number as well after VM). When clicking on the source I find the following function:

 (function () {
     if (document.readyState === "complete") {
         var foundMessageBridge = false
         function notifyMessageBridge() {
            console.log("Notifying Native Hook")
             if (window.__KlarnaNativeHook != null) {
                 console.log("Klarna Native Hook was notified")
                 window.__KlarnaNativeHook.setNativeReady()
                 foundMessageBridge = true
             } else {
                 window.setTimeout(notifyMessageBridge, 500)
             }
         }
         notifyMessageBridge()
     }
     window.addEventListener('load', () => {
         let interval = null
         let notifyMessageBridge = () => {
             if (window.__KlarnaNativeHook != null) {
                 window.__KlarnaNativeHook.setNativeReady()
                 clearInterval(interval)
             }
         }
         interval = setInterval(notifyMessageBridge, 500)
     })
 }())

Which finally led me to that it has something to do with Klarna. Since I'm getting swamped with this I suppose that my app is not getting into the if (window.__KlarnaNativeHook != null).

After some debugging I noticed the following:

When I start the interaction with Klarna my app enters if (window.__KlarnaNativeHook != null). But only once and the spamming resumes afterwards.
If I remove the line (activity as MainActivity).klarnaHybridSDK.addWebView(myWebView) the message swamping stops. Which I suppose is not that surprising.
Apart from my app's web page empty untitled web pages are generated which only prints out "Notifying Native Hook" in the console and nothing else, no code, nothing.
Apart from the swamping the app is working fine with Klarna.

I'm not sure if this is a bug in the SDK or an error of mine.

Any suggestions on how to stop the spamming "Notifying Native Hook"? (I know how to filter it, but 120 messages/min * (my app's webpage + the untitleds generated) and doing it every time is getting tiresome)

Code

MainActivity

        ...
    }
    override fun didHideFullscreenContent(webView: WebView, completion: OnCompletion) {
        Timber.i("Klarna didHideFullscreenContent called")
        completion.run()
    }

    override fun didShowFullscreenContent(webView: WebView, completion: OnCompletion) {
        Timber.i("Klarna didShowFullscreenContent called")
        completion.run()
    }

    override fun onErrorOccurred(webView: WebView, error: KlarnaMobileSDKError) {
        Timber.i("Klarna onErrorOccurred called")
        Timber.i("Klarna Error: $error")
    }

    override fun willHideFullscreenContent(webView: WebView, completion: OnCompletion) {
