            Bug ID: 138732
           Summary: Refactor RenderMathMLOperator to avoid relayout during
                    layout
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: MathML
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: alex at igalia.com

The row layout code checks the stretch distance and this function updates style which causes a layout and width calculation. This should not be required just parsing the values when they change and dividing the updateStyle funcion in two, creating a calculateStretchDistance function.
