In the provided example are a number of charts; by scrolling down and then back up, the ones that are ofscreen render correctly, but the ones that were a part of the document load fail. This may be related to the way that SVG nodes are added to the document by plotkit - the JS actually adds the SVG node itself along with child contents. Would be nice to have this work. :)
One of many many invalidation issues in our current SVG support. It would be nice to reduce this down to a much simpler test case. I'm not even sure what sort of SVG elements PlotKit is creating here w/o looking more at the code.
what's really odd about it is that it's the first one on the page that renders completely; scroll anywhere, and reload, and the first svg block is fine. All of the other SVG blocks don't render.
