Than you for updating the error message!

What are the numbers in square brackets?  Is it sufficient for the user to determine where the problem is?

For example, when I enter a single '{' in the monkey tester CSS Playground -> Custom CSS field, I get the following output:

`WARNING: CSS Error parsing '{: Expected RBRACE at [-1,-1]`

what does `[-1,-1]` refer to?
