Hi @FasihZafar

Thanks for reporting. So yes it looks like the codemirror theme is not being applied at all, and I don't think there is code in place to actually implement it!

In order to apply codemirror theme, it is necessary to load the appropriate css file which thebe is not doing for you. However, even if I manually add the cobalt.css to my page, and set the option it still does not work. Perhaps we need configure codemirror differently in the version we on which is 5.61.1.

Definitely an issue though.
