Wojciech Trocki the showcase application and only happens in iOS, not Android. I'm using Ionic CLI 4.12 and Cordova CLI version 8. The cordova-ios version is 5.0.1 per config.xml:

<engine name="ios" spec="5.0.1" />

This is my first time seeing something like this too. Must be something to do the the WebView Ionic is creating with cordova-plugin-ionic-webview?

I think we should mention this in docs since Ionic accounts for a large amount of Cordova applications and we've chosen it for our showcase too. I got this using the showcase without making changes, so others will run into it too.
