openlayers: GML3 - WFS (DefaultSRS = EPSG:4326) Bad parsing

I have a GetFeature response from WFS server which have EPSG:4326 as default srs :

Example of GetFeature (WFS 1.1.0) Latitude/Longitude format

<gml:MultiCurve>
<gml:curveMember>
<gml:LineString>
<gml:posList>
48.43280195733815 4.7228979270717497 48.432722674997414 4.7228950702474055 ...
</gml:MultiCurve>
</gml:curveMember>
<gml:LineString>
<gml:posList>

GML3 parsing this response like this :

ol.format.GML3.prototype.readFlatPosList_ = function(node, objectStack) {
  var s = ol.xml.getAllTextContent(node, false).replace(/^\s*|\s*$/g, '');
  var context = objectStack[0];
  **var containerSrs = context['srsName'];**
  var containerDimension = node.parentNode.getAttribute('srsDimension');
  var axisOrientation = 'enu';
  if (containerSrs) {
    var proj = ol.proj.get(containerSrs);
    axisOrientation = proj.getAxisOrientation();
  }
...

context[‘srsName’] can change axisOrientation to ‘neu’ (EPSG:4326)

context(‘srsName’] is only setted here :

ol.format.GMLBase.prototype.readGeometryElement = function(node, objectStack) {
  var context = /** @type {Object} */ (objectStack[0]);
  context['srsName'] = node.firstElementChild.getAttribute('srsName');
  ...

Attribute ‘srsName’ not available in geometry node

This method initialize ‘context’ property and ‘srsName’ is never initialized why?

ol.format.WFS.prototype.readFeaturesFromNode = function(node, opt_options) {
  var context = /** @type {ol.XmlNodeStackItem} */ ({
    'featureType': this.featureType_,
    'featureNS': this.featureNS_
  });

In my case, this property is never setted and i can’t change axisOrientation to get geometry coordinates like this :

[ 4.7228979270717497, 48.43280195733815, 4.7228950702474055, 48.432722674997414 … ]

This format is needed to transform coordinates to an other coordinates system.
