They were made on Windows. Remaking them from scratch on Linux. Hmm, the new one seems to work OK in browsers. The Windows and Linux versions of inkscape are only slightly out of sync, and older windows versions (0.48.2) are doing the same thing. Could be a platform issue. I wonder if the windows one will break the linux one if I edit it. No, it stays ok. Very strange. The key difference seems to be that the broken one has:
sodipodi:linespacing="200%"><tspan sodipodi:role="line" id="tspan12-0" x="56.487522" y="368.96161">This is some wrapped</tspan><tspan sodipodi:role="line" x="56.487522" y="393.96161"
where the working one has:
sodipodi:linespacing="200%"><tspan sodipodi:role="line" id="tspan3283-2" x="355.0014" y="452.84192" style="font-size:20px;line-height:200%">This is some wrapped</tspan><tspan sodipodi:role="line" x="355.0014" y="492.84192" id="tspan3285-7" style="font-size:20px;line-height:200%">test with multiple lines</tspan><tspan sodipodi:role="line" x="355.0014" y="532.84192" id="tspan3287-1"
Will update the windows version to match linux exactly and repeat.
