           Summary: className change wont cause a repaint in a special case
           Product: WebKit
           Version: 522+ (nightly)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Major
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: timothy at hatcher.name


While working on a Web Inspector change I ran into this bug.

Changing a className between two elements with a mousedown on one element
removes the className value on another element. The other element will not
repaint when it's className is removed. This only happens when mousedown,
-webkit-user-select: none, background-image and font-weight: bold are used
together. If you change or remove any of those elemnts, this bug goes away. For
example, removing -webkit-user-select: none fixes this. Removing either bold or
background-image fixes this. Changing background-image to just a background
color also fixes this.

See attached test case.
