Uncaught TypeError: this.isSkinW8 is not a function

[J-becirspahic]

When creating a new Editor object, 'this.isSkinW8' is not a function. 'this' might not be referring to the right context. What is strange is that it only happens at line 14615 of the merged JS file. The other 19 calls prior to this one don't cause an error like this.

let options = {}; JSDraw2.Editor("divName", options);
