Huh. I'm afraid I don't know enough about Inkscape or the SVG specs to help with that, just enough to know it's a pain.
Off topic question for you though, that looks like probably i3 or dwm, did you make any modifications to Inkscape to make it more usable in a tiling wm, I always have to turn off tiling when I launch it.
You just have to convert the text in the image to a path before using it wherever you plan on, just be sure to save the original for editing.
