           Summary: Assertion failure (!m_anchorNode ||
                    !m_anchorNode->isPseudoElement())
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mihnea at adobe.com
                CC: koivisto at iki.fi, esprehn at chromium.org

The assertion was added in http://trac.webkit.org/changeset/137336 for WebKitBug https://bugs.webkit.org/show_bug.cgi?id=104462

Load the following HTML snippet in a debug version of WebKit on Mac:

<!doctype html>
<html>
    <head>
        <style>
            #div1:before { display: inline-block; content: "BBB"; border: 1px solid red; }
            #div1 { border: 1px solid green; }
        </style>
    </head>
    <body>
        <div id="div1">AAAA</div>
    </body>
</html>

Click inside the red border of the :before element and you get:
