Hi Radu,
Here is my quick synopsis what I think is going on:
The problem is the OxygenXML SVG rendering engine does not like
FlowRoot. If I convert the SVG to version 1.2 the images show up in Oxygen but fails on publishing.
So:
SVG engine hates "FlowROOT" in SVG 1.1 files.
SVG engine likes "FlowROOT" in SVG 1.2 files
Oxygen does not like SVG 1.2 files
To which someone replied on the Write The Docs Slack channel:
Well, to be fair to Oxygen, SVG 1.2 was never fully developed. In fact, as far as browsers are concerned, it's been rolled into SVG 2.0 development.
See the last section here, "Flavors of SVG":

So I think the real culprit here is InkScape for using something that was was not fully developed in SVG 1.1.
