Markdown Editor compatible with Field: Multilingual Text Box

Hello Jonas,

I started to use Github yesterday, so I’m a bit fumbling in the dark to pull this commit – I’ve no idea if this is the right modus operani for suggesting changes either, so please excuse my noobness.

I wanted to use your nice and synthetic Markdown Editor in combination with the Field: Multilingual Text Box, but the former was messing up the interface when installed:

I dig a little in your code, I changed only a single line and after that the editor works properly. I tested it quickly in the default workspace of Symphony and it was working fine also for the standard textarea.
