Deferring the load handler with a small timeout seems to remedy the issue. \r\n\r\nAlso found that Edge has a bug where it capitalizes several SVG attribute names (`fill=\"red\"` becomes `FILL=\"red\"`), which appears to mess up things across the board. I got downloading to work by using CanVG, but because of this bug the rendering is all wrong.\r\n\r\nCan't promise that I can get all of these browsers to accept embedded images, but at least for normal charts we should have a working fix over the weekend, and graceful fallback to the export server."}}
