@WebsiteDeveloper Since the main selector is a descendent selector, then it matches *any* `div.CodeMirror-cursor.CodeMirror-overwrite` inside `.CodeMirror`, so I don't think this nested identical rule is necessary. All of the other rules with nested `.CodeMirror` simple selectors seems to be for changing the look of an inline editor versus the main editor.

I commented it out and the overwrite cursor seems to work in an inline editor. Any other reason it would be necessary?
