vnd.ogc.gml FeatureInfo parsing

[geoffrowland]

I have a problem with getFeatureInfo parsing from an vnd.ogc.gml source, specifically the BGS Geology 625k WMS:

http://ogc.bgs.ac.uk/cgi-bin/BGS_Bedrock_and_Superficial_Geology/ows

Although, things are working, more-or-less, I always get a duplicate return for a getFeatureInfo request, one containing the expected, appropriately formatted, information, the other is just blank/null. I would like to suppress/hide this blank/ duplicate response. Not mission critical, but still annoying.

I don't know if this is peculiar to the BGS Geology 625k WMS, or a more general issue with parsing vnd.ogc.gml responses

From previous discussion on parsing exotic WMS GetFeatureInfo responses I presume this is handled by terriajs-cesium/Source/Scene/GetFeatureInfoFormat.js

Any insight or fix, gratefully received.
