@cvasseng The fix causes the scatter-smaller test to fail with NaN in the generated SVG....

@TorsteinHonsi I'm not seeing this in neither master or hc5-fixes - are you getting a console error, or is it somewhere in the SVG?

@cvasseng It was in the side-by-side test, but I fixed it. Turned out that the base64 encode image by coincidence contained the letters NaN, so our vigilant test runner put the foot down.
