Editor width with Monaco

I absolutely love having the Monaco editor! One minor annoyance is the width of the editor box when I open a function - with ACE I could drag it larger and it would retain the size after that. With Monaco it defaults to the same narrow width. I know I can expand to full page but it was nice to have to do that every single time I opened a function node. Any way to change the width? I don't think it's a Monaco option because it is coming from the container.

thanks,

Garrett
