            Bug ID: 145568
           Summary: [CSS Box Alignment] Style changes cause excessive
                    invalidations.
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: jfernandez at igalia.com

The Layout Tests located at fast/repaint/{justify, align}-items-* cause an excessive number of unrelated paint invalidations; this is clearly appreciated in the tests expectations. 

After some initial investigation, it seems that the root cause is that changes on those properties cause a style Reattach, so children's xxx-self properties with auto values can be computed again using the new xxx-items value.
