CKEditor version 4.5.8 disabled in IE 11 & Edge - windows

Question

I'm building a hybrid mobile app with the Ionic framework for android, ios, windows 8.1 and windows 10.
I was searching for a good rich text editor and came across CKEditor.
I've tested the editor on an Android and iOS device and it works perfectly.
When i try the editor on a windows device with Internet Explorer 11 or Edge, the editor is disabled (see screenshot below).
The console shows the following error on page initialization:
APPHOST9602: 'javascript:' is an invalid attribute value and will be
ignored. Don’t use 'javascript:' URIs in the local context.
The HTML code i use is :
<div id="ckeditor" ckeditor="options" ng-model="survey.Comments" ready="onReady()"></div>
And my controller:
angular.module('app.parts')
.controller('CommentsController', function ($scope, App, $ionicHistory, Survey) {
$scope.survey = Survey.getSurvey();
// Editor options.
$scope.options = {
language: 'nl',
allowedContent: true,
basicEntities: false,
resize_enabled: false,
startupFocus: true
};
// Called when the editor is completely ready.
$scope.onReady = function () {
// ...
};
});
I use the CKeditor library in combination with lemonade's ckeditor angularjs wrapper
According to the CKEditor specs, the editor should be working on IE 11 and Edge.
To be clear, the CKEditor is disabled on a Windows device (Surface Pro 3 with Windows 10 and laptop with Windows 8.1). When I test CKEditor in Internet Explorer 11 or Edge webbrowser on my laptop, it works fine.
I've also tested with CKEditor < 4.4.8 and using the following code snippet:
CKEDITOR.env.isCompatible = true;
Unfortunately, no success.
Anyone else had or has the same issue and knows how to fix it?
Thanks in advance
