Using Options & root selector, error w/ document.querySelectorAll

[Barton Hammond]

I'm trying to ignore a large section of the page so using the Options, I set the 'root' as div#primary and left the selectors as can be seen in the image below.

and here is the object input parameter to the function setDefinitions(input)

If I try these commands in the console:

Error in event handler for runtime.onMessage: SyntaxError: Failed to execute 'querySelectorAll' on 'Document': 'a.btn.btn-default.dropdown-toggle.' is not a valid selector.
