Conversion of "Popular Visualisation CRS" projection in MapInfo tab file is faulty

MapInfo? 10.5 allows the user to draw polygons on top of background images provided by Virtual Earth. If you do this, the resulting polygons have the "Popular Visualisation CRS" projection (EPSG: 3857).
When read by OGR, this projection is not converted correctly, resulting in a significant shift in the polygons. It appears that the spheroid definition is not set correctly, as it ends up being set to SPHEROID["unknown",6378137,298.257223563], instead of SPHEROID["Popular Visualisation Sphere",6378137,0]
The attached file should display this issue
