    <rdar://problem/7458272> REGRESSION (r50470) Reproducible ASSERT in
    RenderWidget::setWidgetGeometry()
    
    Reviewed by Darin Adler.
    
    WebCore:
    
    Test: fast/forms/defer-updateFromElement.html
    
    * html/HTMLFormControlElement.cpp:
    (WebCore::updateFromElementCallback): Added this post-attach callback
    that invokes updateFromElement().
    (WebCore::HTMLFormControlElement::recalcStyle): Instead of calling
    updateFromElement(), enqueue a post-attach (in this case, post-style
    recalc) callback to do it. updateFromElement() can cause the selection
    to change, and in turn trigger synchronous layout, so it must not be
    called during style recalc.
    
    LayoutTests:
    
    * fast/forms/defer-updateFromElement-expected.txt: Added.
    * fast/forms/defer-updateFromElement.html: Added.
