OpenLayers incorrectly interpreting WFS request when polygon contains repeating vertex

[LewisCorker]

Using OpenLayers 2.12-rc4.

When there is a vertex which appears three times in a polygon (start, middle and end), it is not correctly interpreted. The images attached demonstrate the error.

The GeoJSON response for these polygons is below and the coordinates 112995.56511964,902719.41912787 (highlighted in Bold) appear 3 times:
