only one contour and no Infills added to .svg when exporting 3D-object to svg (files>slice to svg)

[Patlax]

Describe the bug
When slicing one 3D-object using "files>slice to SVG" only one contour, meaning the outer contour of the object, of all detected contours in layer->slices is being written to the svg-file. Infills (4) and any other contours, also outlier contours (see 1,2,3) are ignored fully and the single contour is filled with color. But there have to be more contours then this one, because when printing out the number of contours of layer->slices, mostly a higher number than 1 is being printed to the svg. Additionally, why is each layer defined as a solid layer, without the possibility of including infills like polygons or stars, ...?

3D Model and Slic3r Configuration Export
Please upload a ZIP archive containing a copy of the 3D model you are seeing this bug with and a CTRL-E export of the configuration used.

Expected behavior
All contours incl. the infills shall be printed to the svg-file like in the layer-preview in this picture, shouldn´t they?
