           Summary: Necessary reflow not triggered with specific
                    combination of getSelection, positioning and :hover
                    rule
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
               URL: http://jsfiddle.net/Fncec/1/
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: webkit_bugs at juima.org


See the jsfiddle minimal testcase. On mouseup, all ranges are removed from a selection (this appears a necessary part of the testcase, though might just have a necessary effect I haven't been able to isolate), and a class gets set on an image, removing a margin and setting a near identical border. The image should remain in the same position, but instead jumps away. A further hover triggers a reflow back to the correct position.
Seen on Chromium Version 25.0.1364.160 Ubuntu 12.04 (25.0.1364.160-0ubuntu0.12.04.1) and confirmed to still exist on a nightly on OS X.
