upgrading to 4.4.1 causing error "Cannot read property 'settings' of undefined"

Tinymce is created dynamically , and the code to create is as follows

var ed = new tinymce.Editor(this.id, { settings }, tinymce.EditorManager);
        var self=this;
        this.ed.on('keyup',()=> {
          self.model = self.ed.getContent();
        });

        this.ed.render();

is it bug? any help please

I use bower for my plugins. I switched to tinymce.js (instead of tinymce.min.js), then it works. This problem is there since v4.4.0 (currently I use 4.5.2)

The minified-versions are broken…
