Textarea cursor removal after insertText

[lance13c]

If there is a textarea and a div that is the Quill Editor. When the textarea has focus and then a insertText method is called. The cursor disappears from the textarea.

One solution is to comment out the this.setNativeRange(null); in setRange(range) function.
