           Summary: Getting the descriptor selectionDirection throws error
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

        AssignedTo: webkit-unassigned at lists.webkit.org

var checkbox = document.createElement('input');
input.type = 'checkbox';
Object.getOwnPropertyDescriptor(input, 'selectionDirection');  // THROWS!

It is OK to throw when we try to get the value of the selectionDirection but is an ES5 spec violation to throw on getting the descriptor.

This is most likely because we report WebIDL attributes as data properties, and as such, we read the value of the property.
