           Summary: [Refactoring] Remove elementParentStyle from
                    SelectorCheckerContext
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: CSS
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: tasak at google.com


Currently elementParentStyle is not used in SelectorChecker and StyleResolver.

A parent style was used to cache whether a child of the parent node matches some n-th, first-child, last-child selector. The information was used to check whether a given element can share its sibling element's style or not. 
However, now the information is stored in a parent element, not style. So we don't need to provide elementParentStyle for SelectorChecker.
