Issue getting rules for non-completed angular page

[jadrake75]

If the ng:cloak is being used the selectAll query on window.document fails in chrome (I assume other browsers too). I believe either a check for classes/rules with "[" or catching and skipping exception is needed.

26 Error: Failed to execute 'querySelectorAll' on 'Document': '[ng:cloak]' is not a valid selector.
