Okay, so apparently #drawIO does not export #SVG as proper SVG..... the texts are embedded in some HTML elements...
Firefox can render it perfectly, but when using some tool like #Inkscape , the text is a raster graphic.
When turning off font embedding and XML inclusion of the diagram within the SVG file, when exporting from drawIO, Inkscape can at least load the text as text, but it is weirdly truncated and does not stay within its bounds.
What the hell is this?
Edit: Pinging @drawio - perhaps you guys have an idea? :D
