    // GWT's DataGrid implementation adds a handful of nodes with aggressive
    // inline styles in the header and footer of the grid. They're designed to
    // help with scrolling, but in newer versions of Chromium, they cause
    // horizontal overlay scrollbars to appear when the grid is created and
    // whenever it's resized. The below tweaks these elements so that they
    // don't have a scrollbar.
    //
    // Typically we'd use CSS here but these elements are buried, have no
    // assigned class, and have all their style attributes applied inline, so
    // instead we scan the attached DOM subtree and change the inline styles.
