            Bug ID: 156954
           Summary: [Win] The function findTopLevelParent should return
                    the first window which is not a child.
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Misc.

The function findTopLevelParent is used when the active state of the browser is determined. It usually works very well, but when there is a window with the style WS_POPUP in the hierarchy which has a parent, the function will not return this window, but keep walking the hierarchy. A window with the WS_POPUP style cannot have the WS_CHILD style, and is a type of top level window, even though it can have a parent/owner.
