I haven't look at the blink issue (thank you for linking to it) but I bet this is a bug in our legacy inline layout which is what svg text rendering still based on. We are in the middle of moving svg text (layout and) rendering over on top of IFC. Hopefully this progresses as well -though I don't want to discourage anyone from giving a shot to this.

In Blink, it was fixed with SVG Text Layout re-write similar to their LayoutNG, so it might be something definitely broken in our SVG Text rendering code relying on old Legacy Layout code.
