           Summary: hitTest() on a single line input only works through
                    happenstance.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Forms
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: simon.fraser at apple.com


Hit testing on a RenderTextControlSingleLine seems to work only because of a
side-effect of HitTestResult behavior.

What I see happening is this.
RenderLayer::hitTest calls hitTest() on the renderer, which goes into
RenderTextControlSingleLine::nodeAtPoint(). This ends up setting the
TextControlInnerTextElement as the innerNode() on the result. However,
RenderTextControlSingleLine::nodeAtPoint() then returns false!

So we continue to hit test all the way up to the body. The body's layer ends up
being the one hit, but we use the node in the result anyway.

This is hurting my karma. See bug 24312.
