           Summary: REGRESSION (r40180): Scroll wheel events over text
                    scroll the page instead of the ancestor overflow
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
               URL: data:text/html,%3Cbody%20style=%22height:%20300%%22%3E%3
                    Cdiv%20style=%22height:%20200px;%20overflow:auto;%22%3E%
                    3Cdiv%20style=%22height:%20400px;%22%3Etext
        OS/Version: Mac OS X 10.5
            Status: NEW
          Keywords: HasReduction, Regression, NeedsRadar
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org

To reproduce: open the URL and position the mouse pointer over the text. Use
the mouse wheel to scroll down.

Expected result: the overflow area should scroll.

Actual result: the page scrolls until the text is no longer under the mouse,
then the overflow area begins to scroll.

Regression: apparently caused by r40180.
