     This testcase ensures that we repaint correctly when "object-fit" is

     adjusted on a replaced element with SVG content.  We start with

     "object-fit: contain", which lets some of the red background show through

     as we fit the SVG's square aspect-ratio into the wide rectangular

     container elements. We then change dynamically to "object-fit: cover",

     which should scale our SVG content to cover each replaced element's

     content-box. No red should ultimately be visible in the reftest snapshot.
