This is a bug that we have discovered in the latest version and are working on a fix for. We are aiming to get a fix for this out as soon as possible. Adding extra nodes between the first and second nodes of the SVG can reduce the effect of this bug in the meantime.
Good to hear.
I imagine this will mean I might need to remove the nodes I added to compensate for this then. Oh well, guess I'll just wait til I'm finished this project before upgrading.
