IE 8 does not support SVG, so the VML is selected by OpenLayers for vector
rendering.

In that case the Canvas renderer is selected.

Indeed. IE 9 supports SVG while IE 8 does not.


This makes it clear that the bug is in OpenLayers' SVG renderer, and that
the Canvas and VML renderers work correctly.
