           Summary: DOMSelection shouldn't instantiate VisibleSelection
                    everywhere
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: HTML Editing
        AssignedTo: webkit-unassigned at lists.webkit.org

Right now, various member functions of DOMSelection instantiates VisibleSelection.
This would mean that all those functions are triggering synchronous layout at that point.

Defer those synchronous layout until FrameSelection's member functions are called
so that we may optimize them later in the bug 127832.
