https://www.w3.org/Bugs/Public/show_bug.cgi?id=25958

            Bug ID: 25958
           Summary: TypeError or SyntaxError for querySelector() and
                    querySelectorAll()
           Product: WebAppsWG
           Version: unspecified

                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P2

If matches() was changed:

https://www.w3.org/Bugs/Public/show_bug.cgi?id=24028

then what about querySelector() and querySelectorAll()? This methods are older
than matches(), but still in "scope-match a selectors string " algo we have:

2. If s is failure, throw a JavaScript TypeError. 

Firefox, Chrome and IE return DOMException "SyntaxError", not JavaScript
TypeError (query() and queryAll() still not supported so skipping them). This
behaviour is correct per Selectors API Level 1/Selectors API Level 2:

http://www.w3.org/TR/selectors-api/#parse-a-selector
http://dev.w3.org/2006/webapi/selectors-api2/#parse-a-selector

so really any implementators wants/plans change this?
