There is an extra dividing line in the edit box

Thank you very much to the author for making such a good project. I encountered such a situation while using it yesterday.

It's editor's print-margin line.
If you want to hidden this line, you can handle it in onEditorLoaded like this

<md-editor (onEditorLoaded)="onEditorLoaded($event)"></md-editor>

onEditorLoaded(editor) {
  editor.setShowPrintMargin(false);
}

thank you very much。
