Setting className for SVG element will raise error, here’s some stack trace, I’m using the non minified js version. I thinks the reason is probably I’m using fontawesome 5 SVG icon

@niklasvh, will you please release v1.0.0-rc.6 with this fix? What do you need to make this happen soon?

@niklasvh, the community using this library expects more frequent updates than you are providing. (>3 months of inactivity) If you are unable to maintain this library on your own, please add some prominent contributors such as @andyedinborough and @cobexer as collaborators: https://github.com/niklasvh/html2canvas/settings/access. Maybe they can provide the maintenance and releases that this library needs. Thank you.
