Markdown scroll when it's one line

[yutuo]

I tested it at chrome 48.0.2564.109.

1. Open the site https://codemirror.net/
2. Delete CodeMirror's text, leave one line(eg.<!-- Create a simple CodeMirror instance -->).
3. Move mouse to CodeMirror. CodeMirror can scrol.

I'am sorry, My English is poor.

The demo at http://codemirror.net does not show a scrollbar when there's only a single line in it, neither could I scroll it with the scroll wheel. What kind of scrolling do you mean?

It's not scrollbar.

When CodeMirror has only a single line, The text in CodeMirror will up and down when the mouse are scrolling
