Solve a [problem](https://github.com/codemirror/CodeMirror/issues/3821) where the horizontal scrollbar could hide text in Firefox.

[Markdown mode](http://codemirror.net/mode/markdown/): Fix [issue](https://github.com/codemirror/CodeMirror/issues/3787) where the mode would keep state related to fenced code blocks in an unsafe way, leading to occasional corrupted parses.
