Error while beautifying CSS

[Misiu]

I'm in middle of building sample app in fiddle and I wanted to format my CSS.
After clicking "Beautify all open files" nothing is happening and in console I get tis error:
Uncaught TypeError: undefined is not a function
Here is my fiddle:

That fiddle doesn't have any CSS files in it.

I don't have separate CSS file, but I have some CSS in my HTML page.
Steps to reproduce: Open Fiddle -> select index.html from Fiddle Resources -> click Beautify all opened files -> see error in console.
