Currently floating images specified using the VML shapes are imported as non-floating, for example:

<v:shape id="_x0000_s1026" type="#_x0000_t75" style="height:180.25pt;margin-left:62.25pt;margin-top:1.65pt;position:absolute;width:180.25pt;z-index:251658240" o:preferrelative="t">
        <v:imagedata r:id="rId4" />
</v:shape>
